what Americans pay for their cars

I am not a member of the 1% by any means, but one key to my personal financial stability has been not owning a car for the last 21 years. People shell out enormous amounts of their income to buy, lease, maintain, repair, replace, and park personal vehicles. And that doesn’t count what you are paying in terms of your home value, property taxes, and gas taxes to maintain all that car focused infrastructure out there. Nor does it count injuries and deaths due to crashes (well, to some extent you pay for that through your car insurance and health insurance), and certainly not the costs of obesity, heart disease, and diabetes due to the opportunity cost of driving relative to spending that same time on some form of physical activity. Finally, people and nature are paying the costs in terms of air and water pollution and heat in more abstract ways (pain, death, knowing ecosystems are being destroyed) if not in dollars.

And of course, for many communities people choose to live in, that personal vehicle is absolutely necessary to get to jobs, school, and put food on the table. I’m just saying where you choose to live is a choice, at least in the longer term. If you want to live in a less car dependent community, you may not be able to change your situation overnight but you could set a goal to change your situation say within 3-5 years. Anyway…

This Jacobin article (which is an unapologetic socialist magazine?) has some interesting facts and figures on what Americans are spending on their private cars.

The country just crossed over a critical threshold last month: 5.1 percent of car owners are at least ninety days delinquent on their loans. This is almost touching the record high of 5.3 percent, reached during the nadir of the Great Recession in 2010. Young people are unsurprisingly hardest hit, with 7.5 percent of car-owning Gen Zers delinquent. The trend for all is upward for the past eight quarters — and expected to continue.

Auto insurance rates are up 56 percent in the past five years; car repossessions are also at post-Recession highs, at 1.73 million so far this year; and car repair costs popped 32 percent in the past two years alone, exacerbated by Donald Trump’s new tariffs. In 2023, a Federal Reserve Bank survey found that car repairs won out over rent, mortgage, health care, and food as the cost that Americans were most concerned about.

Consumers have responded to all this pressure by extending the terms of their loans to decrease their average monthly payments. Yet interest rates have kept rising. The average American is forking over between $550 and $750 a month on their car note, a number that used to be a monthly rent a decade prior. Today 20 percent of all newly originated car notes are over $1,000 a month, and you’d be mistaken to think that only the top income quintile is represented in that number.

$500-1000 per month is a lot of money, and I think that is just the loan payment.

building public transit faster and cheaper

Haden Clarkin, in a blog called The Transit Guy offers a “four step playbook” for building public transportation infrastructure in the United States. I’ll summarize and offer a few of my own reactions in brackets.

  • Develop a comprehensive vision, goals, and plan. [Yes, a lot of times people – especially my fellow engineers but also politicians trying to be helpful with funding – want to jump directly to “projects”. A “project” is a specific thing you want to build in a specific place. But it needs to be part of a larger plan to serve a larger purpose in the long term. This planning needs to be firmly in place when the “project” ideas come up and people are pushing for quick decisions on them. And you need a critical mass of people inside the organizations making the decisions, from senior management down to at least mid-level management, to really understand and buy into the plan. And you need to bring new people on board with the plan as you gradually lose institutional knowledge to political churn and attrition.]
  • Approve the plan through a voter referendum. In Haden’s vision, this cuts through a lot of the regulatory red tape later, because all the regulatory requirements tend to have extensive public buy-in and outreach requirements. A state-level referendum may also cut through some of localized NIMBY issues. [He’s writing in Rhode Island, and this may work there. We don’t really have state-level referenda in Pennsylvania, and I assume there is probably some constitutional reason for this. There are mechanisms for updating the constitution, and maybe we should work on this. We do have a big urban-rural divide issue in the state though, like many larger states. This might make it difficult to pass a state-level referendum focused on a metro area. It may be worth a try though.]
  • “Design and Plan it In-House”. [This is consultant hate. I happen to be a consultant who has worked with and been embedded within public agencies, and I think this is hogwash. Well, mostly hogwash. Sometimes public sector people mistakenly compare the hourly direct labor cost for their own people to the hourly cost of labor+benefits+overhead+profit of private sector consultants. Yes, there is a small profit in there, theoretically set by market competition. Competition for public-sector contracts is pretty ferocious, at least outside of the military-industrial complex. The true overhead and benefits cost to the public sector is often hard to define, but if you do an honest accounting of it, it is almost certainly higher than the private sector. Now, you want a public agency firmly in control of design, procurement, and construction of its projects. So it probably makes sense to set some benchmark like the majority of people working on a project should work for the public agency. But then it can make a lot of sense to bring in consultants both for their expertise and because they are a flexible work force you can surge in when needed and then scale back when no longer needed. You let them deal with those overhead and benefit costs so they don’t get out of control on the public side. You want strong technical people on the public side of course, but it is also really important to focus on strong project management, procurement, finance and accounting, and construction management expertise so you can make the best use of the private sector.]
  • Prioritize high impact and publicly visible projects first. [This makes total sense. I especially like the idea of building bus rapid transit lines early and converting them to light rail or even subway over time.]

There’s lots more, of course. Land use, housing, and zoning policy all play a role in building communities where there will actually be demand and support for public transportation. You probably need metro-scale and often multi-state authorities for design, construction, operation, and financing. That is big picture, long term context for the planning process. In my fantasy world, we wouldn’t just have a transportation plan for one municipality, but a comprehensive infrastructure plan (how about transportation, energy, water, communications, green infrastructure and food) at the metropolitan area scale.

Philadelphia transit cuts

It’s sad – Philadelphia’s public transportation, which was already creaky and unreliable due to decades of deferred maintenance and capital investment, is being financially starved due to dysfunctional politics at the state level. At the heart of the political game is a willful misunderstanding of a fundamental truth – most economic activity occurs where the most people are. Is this really not so obvious that we need to debate it? And this means that most taxes in a state like Pennsylvania are paid in its metropolitan areas. It makes sense to spend some of that money disproportionately in rural areas which by definition can’t generate the net economic activity to support themselves. But people and politicians in these rural areas not only do not appreciate this, they believe the exact opposite thing to be true – that they are subsidizing metropolitan areas. Which is logically, financially, and physically impossible. But mirroring the larger country, these irrational rural politicians have disproportionate political power relative to the number of people they represent. I have no political answers to this political problem, and I am getting closer to considering leaving the state. Delaware and New Jersey have their own problems but are much more rationally governed.

Anyway, having said all that, Philadelphia’s public transportation is not exactly cutting edge or visionary. It’s dirty, old, slow, and communication is poor. And it’s not cheap – one person riding a bus can save money relative to Uber, assuming they don’t place a high value on time. But several people traveling together will not save money. Tourists and business travelers have no hope of understanding it, if they were willing to brave the urine and feces and garbage and rats in the stations and bus stops and on the vehicles themselves. A system like this is at risk of losing out to more innovative competition, even if that innovative competition is bad for the environment and dangerous for people. So let’s look at some of the alternatives mentioned in this ABC article.

  • ride sharing databases – The local one is run by our metropolitan planning organization. Basically just a message board for people to find each other who want to carpool. Makes sense, just seems low tech and clunky. Enterprising individuals could probably build a business around this, which may or may not be against the rules.
  • Rideshare (Uber, etc.) – Sure they’ve been around for awhile, but they have some new ideas. With “Group Rides”, you can invite specific friends to share your ride. “The company’s latest option, Route Share, is designed to function like a commuter shuttle running every 20 minutes during peak times from 6 a.m. to 10 a.m. and 4 p.m. to 8 p.m.. with designated pick-up and drop-off points.” … “For even more significant savings, try Uber Transit, which provides a public transit route, sometimes combined with an Uber ride.”
  • van pools run by rental car companies – “The rental car company teams up with companies to match employees who live near each other, then provides them with vehicles to use… Each ride consists of 4-15 riders who live near each other or along a route, and share rides to and from work. Enterprise takes care of maintenance and vehicle liability insurance.”
  • New Jersey and Delaware also have “Transportation Management Associations” which seem vague to me but again have something to do with organizing carpools and vanpools.

A couple thoughts. First, we see tech solutions like Uber adapting to public transportation, and starting to cover the gap between whatever public transportation can provide and what people actually need to get from Point A to Point B. This is basically good, although if public transportation can’t compete on cost it may eventually disappear. Governments might do the math and decide to subsidize the more flexible private options instead. Self-driving and self-parking wheeled vehicles may change the dynamics of how all this works, and relatively soon. All of this is likely to exacerbating sprawling land uses rather than the more compact urban areas we know are best for economic growth, innovation, human health, and the environment. But that has been the trend for a century at least.

I have some hope that self-parking vehicles may enable less waste of the most economically valuable land for parking. Because the point of parking is to make transportation easily accessible where you are working/shopping/recreating, and a self-driving vehicle can park efficiently farther away but still show up when and where you need it. Instead of a store having to have a parking lot that is bigger than the store, you can now have two stores next to each other and a large parking lot/garage out of sight on the edge of town. And that garage or lot won’t have to be as big because the self-parking cars will be able to maneuver more efficiently not to mention infinitely patiently compared to human drivers.

Telecommuting and work travel in Australia

This might seem esoteric, but it is somewhat germane to some points I made recently. One part of a big-picture solution to housing supply challenges lies in, well, housing. But another angle (at least from an economic growth perspective) lies in transportation and telecommunications infrastructure allowing people to live in one place and work in others with less friction (i.e., travel time and cost.)

A tale of two cities: Patterns and drivers of Australia’s intercity non-local employment from an industry perspective

Under conditions of spatial mismatch between labor supply and demand, intercity non-local employment, including intercity-commuting-based employment and remote work, has become increasingly common worldwide. However, research examining intercity non-local employment from an industry perspective remains limited. Using census data from 2011, 2016, and 2021 for Australia’s significant urban areas, this study adopts an industry lens to examine patterns of intercity non-local employment and their associations with industry diversity, industry disparity, and the location quotients of different industries. The findings reveal that: (1) Intercity non-local employment in Australia intensified during 2011–2021, with Sydney, Melbourne, Brisbane, Adelaide, and Perth serving as key network nodes; (2) Although industry diversity is not significantly associated with non-local employment, work-residence connections are more likely to form between industrially diverse cities over longer distances; (3) Industry disparity between work and residential cities reduces the likelihood of non-local employment, reflecting a tendency toward employment self-containment; (4) Cities with higher location quotients in agriculture, mining, and manufacturing exhibit a stronger capacity to attract non-local workers. This study supports developing regional industrial diversity centers as hubs for labor mobility and interaction. Furthermore, it highlights the rationality of industry complementarity, particularly between capital and non-capital cities, as a strategy to balance labor supply and demand, and calls for further evaluation of the long-term impacts of non-local employment on cities reliant on specific workforce sectors. Overall, this research advances the understanding of Australia’s urban structure and offers valuable insights for targeted industrial development strategies aimed at fostering balanced and sustainable urban systems.

I did work and travel in Australia a bit about 10-15 years ago, and one thing that struck this American is that their cities are just really far apart, and there is not much in between. So I got the impression that a lot of their white collar business travel is by plane. What is blue collar business travel you ask – there I am thinking of long haul trucking. And no, if I am thinking about long haul trucking in Australia I can’t get Mad Max out of my head. One really hopes this is not our future.

Roundabouts

Roundabouts are not really cutting edge, but they are new to many of us in the slow-on-the-uptake Commonwealth of Pennsylvania. Here’s a video on what you are supposed to do.

Youtube

One thing drivers are NEVER supposed to do is pass a bicyclist in the lane, in a roundabout or anywhere else. I observe that most drivers and bicyclists are confused about this. Not only do bicyclists often hug the right edge of the lane, drivers tend to speed up as they pass them, which is going to be deadly if anything unexpected happens. Under our state law, cars have to give bikes 4 feet of space. Lanes are around 12 feet wide, so this means a car centered in the lane cannot physically pass a bike legally. Police do not enforce this rule, and signs stating it are very rare. We occasionally see the “BIKES MAY USE FULL LANE” sign, but a better sign, which I have seen in other states, adds “CHANGE LANES TO PASS”. Separated, protected lanes for low-momentum zero emissions vehicles with their own signals at intersections would be the superior, most modern way to go, of course.

January 2025 in Review

Well, January was a doozy. Here goes:

Most frightening and/or depressing story: Longreads #1 stories of 2024 – this is a lookback but I posted it in January and it has a ton of interesting stuff. Interesting, frightening, and depressing. The story on Israel’s dispatching of air strikes based on statistical analysis is the single most disturbing article I read last year. Everyone should read this article and decide for yourselves where you stand. Another one is called “When the Arctic Melts”. Even as the shadow of fossil fuel propaganda once again overspreads the land, I am afraid the globe could be approaching an irreversible tipping point into runaway warming and sea level rise. Let’s hope the world can afford another four-year round of U.S. backsliding and then pick up the pieces, but I am not sure.

Most hopeful story: I noted that congestion pricing in New York City could provide a glimmer of hope that transportation in the United States could begin to implement 21st century international best practices. (Yes, I am aware the century is a quarter over already – one more indicator of the U.S. slipping towards the bottom of the world’s more advanced nations.) Unfortunately, as I write this on February 13 we see the President himself actively interfering in this state and local matter. “States’ rights” for thee, not for me (i.e. only when it’s convenient to some disingenuous argument).

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: AI agents – coming soon to a computer near you.

2024 in Review

Intro

What I do here is list all the posts I picked each month as most frightening, most hopeful, and most interesting. Then I attempt some kind of synthesis and analysis of this information. You can drill down to my “month in review” posts, from there to individual posts, and from there to source articles if you have the time and inclination.

Post Roundup

Most frightening and/or depressing stories

  • JANUARY: 2023 was “a year of war“, and so far 2024 is not looking better. Those diplomatic grand bargains you always hear about seem to be getting less grand. And the drumbeat for a U.S. attack on Iran got louder.
  • FEBRUARY: The war on terror continues, and the propaganda umbrella has expanded to cover attacks on any group labeled as “Iran-backed”. Fentanyl gets an honorable mention, but affects mostly the poor and miserable whereas the war on terror threatens to immolate us all.
  • MARCH: Ralph Nader says the civilian carnage in Gaza is an order of magnitude worse than even the Gaza authorities say it is. Which is almost unthinkably horrible if true, and makes the Israeli public statements about collateral damage seem even less credible. However even handed you try to be in considering this war could be a proportionate response to the original gruesome attack, it is getting harder.
  • APRIL: Peter Turchin’s description of a “wealth pump” leading to stagnation and political instability seems to fit the United States pretty well at this moment. The IMF shows that global productivity has been slowing since the US-caused financial crisis in 2008. In Turchin’s model, our November election will be a struggle between elites and counter-elites who both represent the wealthy and powerful. That sounds about right, but I still say it is a struggle between competence and incompetence, and competence is a minimum thing we need to survive in a dangerous world. In early April I thought things were trending painfully slowly, but clearly, in Biden’s direction. As I write this in early May I am no longer convinced of that.
  • MAY: What a modern nuclear bomb would do to a large modern city. Do we already know this intellectually? Sure. Do we constantly need to be reminded and remind our elected leaders that this is absolutely unthinkable and must be avoided at any cost? Apparently.
  • JUNE: Some self-labeled “conservatives” in the United States want to do away with the National Oceanic and Atmospheric Administration, the Census Bureau, the Internal Revenue Service, the Federal Emergency Management Agency, the National Institutes of Health, the Department of Education, and possibly even the Federal Reserve. All these are needed to have a competent, stable government and society and to be prepared to respond and recover from the shocks that are coming, so I would call this nihilist and not “conservative” at all. How is it conservative to want to destroy the institutions that have underpinned the success of our nation thus far? On the other hand, they also want to double down on the unimaginative pro-big-business, pro-war consensus of the two major parties over the last 50 years or so, which has also gotten us to where we are today. And it looks like the amateurs and psychopaths have the upper hand at the moment in terms of our November election. This is certainly not “morning in America”.
  • JULY: Joe Biden’s depressing decline in the international spotlight, and our failed political system that could let such a thing happen. Not much more I can say about it that has not been said. The “election trifecta” – non-partisan, single ballot primaries; ranked-choice general elections; and non-partisan redistricting – is one promising proposal for improving this system.
  • AUGUST: Human extinction, and our dysfunctional political system’s seeming lack of concern and even active ramping up the risk. We have forgotten how horrible it was last time (and the only time) nuclear weapons were used on cities. Is there any story that could be more frightening and/or depressing to a human?
  • SEPTEMBER: There is nothing on Earth more frightening than nuclear weapons. China has scrapped its “minimal deterrent” nuclear doctrine in favor of massively scaling up their arsenal to compete with the also ramping up U.S. and Russian arsenals. They do still have an official “no first strike” policy. The U.S. by contrast has an arrogant foreign policy.
  • OCTOBER: When it comes to the #1 climate change impact on ordinary people, it’s the food stupid. (Dear reader, I’m not calling you stupid, and I don’t consider myself stupid, but somehow we individually intelligent humans are all managing to be stupid together.) This is the shit that is probably going to hit the fan first while we are shouting stupid slogans like “drill baby drill” (okay, if you are cheering when you hear a politician shout that you might not be stupid, but you are at least uninformed.)
  • NOVEMBER: Ugh, the U.S. election. I don’t really want to talk or think too much more about it. What’s really frightening to me is the celebration of irrationality. With incompetent, irrational clowns and fools now in charge of everything, any crises or emergencies that arise are not going to be dealt with rationally, competently, or at all. And this is how an emergency can turn into a system failure. Let’s hope we can muddle through four years without a major acute crisis of some kind, but that is hard to do.
  • DECEMBER: The annual “horizon scan” from the journal Trends in Ecology and Evolution lists three key issues having to do with tipping points: “melting sea ice, melting glaciers, and release of seabed carbon stores”.

Most hopeful stories

  • JANUARY: According to Bill Gates, some bright spots in the world today include gains in administering vaccines to children around the world, a shift toward greater public acceptance of nuclear power, and maybe getting a bit closer to the dream of fusion power. He pontificates about AI, and my personal sense is it is still too soon, but AI does hold some promise for speeding up scientific progress.
  • FEBRUARY: The people who are in charge of the USA’s nuclear weapons still believe in the ideals behind the founding of the country, at least more than the rest of us. Okay, this is lean times for hope, but seriously this at least buys us time to figure some stuff out.
  • MARCH: Yes, there are some fun native (North American) wildflowers you can grow from bulbs. Let’s give the environmental and geopolitical doom and gloom a rest for a moment and cultivate our gardens.
  • APRIL: Some tweaks to U.S. trade policy might be able to significantly ease the “border crisis” and create a broad political coalition of bigots, big business, and people who buy things in stores.
  • MAY: The U.S. might manage to connect two large cities with true high speed rail, relatively soon and relatively cost effectively. The trick is that there is not much between these cities other than flat desert. The route will mostly follow an existing highway, and we should think about doing this more as autonomous vehicles very gradually start to reduce demand on our highways in coming decades.
  • JUNE: Computer-controlled cars are slowly but surely attaining widespread commercial rollout. I don’t care what the cynics say – this will save land, money and lives. And combined with renewable and/or nuclear energy, it could play a big role in turning the corner on the climate crisis.
  • JULY: A universal flu vaccine may be close, the same technology might work for other diseases like Covid, HIV, and tuberculosis.
  • AUGUST: Drugs targeting “GLP-1 receptors” (one brand name is Ozempic) were developed to treat diabetes and obesity, but they may be effective against stroke, heart disease, kidney disease, Parkinson’s, Alzheimer’s, alcoholism, and drug addiction. They may even be miracle anti-aging drugs. But really, it seems like the simple story is that most of us in the modern world are just eating too much and moving our bodies too little, and these drugs might let us get some of the benefits of healthier lifestyles without actually making the effort. Making the effort, or making the effort while turbo-charging the benefits with drugs, might be the better option. Nonetheless, saving lives is saving lives.
  • SEPTEMBER: AI should be able to improve traffic management in cities, although early ideas on this front are not very creative.
  • OCTOBER: AI, at least in theory, should be able to help us manage physical assets like buildings and infrastructure more efficiently. Humans still need to have some up-front vision of what we would like our infrastructure systems to look like in the long term, but then AI should be able to help us make optimal repair-replace-upgrade-abandon decisions that nudge the system toward the vision over time as individual components wear out.
  • NOVEMBER: In a nation of 350 million odd people, there have to be some talented potential leaders for us to choose between in future elections, right? Or is it clowns and fools all the way down? Sorry folks, this is how I feel.
  • DECEMBER: I’m really drawing a blank on this one folks. Since I reviewed a number of book lists posted by others, I just pick one book title that sounds somewhat hopeful: Abolishing Fossil Fuels: Lessons from Movements That Won.

Most interesting stories, that were not particularly frightening or hopeful, or perhaps were a mixture of both

  • JANUARY: The return of super-sonic commercial flight is inching closer.
  • FEBRUARY: I am not a great chef by any means, but all hail recipe websites, however pesky they may be, for helping me make edible food.
  • MARCH: I looked into Belarus, and now I am just a little bit less ignorant, which is nice.
  • APRIL: If the singularity is in fact near, our worries about a productivity slow down are almost over, and our new worries will be about boredom in our new lives of leisure. It doesn’t seem like a good idea to count on this happening in the very near future, and therefore stop trying to solve the problems we have at the moment. This would be one of those “nice to have” problems. If it does in fact materialize, the places to be will be the ones that manage to shut down Peter Turchin’s wealth pump and spread the newfound wealth, rather than the places where a chosen few live god-like existences while leaving the masses in squalor.
  • MAY: Drone deliveries make some sense, but what we really need is infrastructure on the ground that lets all sorts of slow, light-weight vehicles zip around in our cities efficiently and safely. And this means separating them completely from those fast, heavy vehicles designed for highway travel.
  • JUNE: I had a misconception that if the world reduces greenhouse gases today, the benefits will not kick in for decades. Happily, scientists’ understanding of this has been updated and I will update my own understanding along with that. The key is the ocean’s ability to absorb excess carbon dioxide from the atmosphere relatively quickly. (I am not sure this is good for the ocean itself, but it is somewhat hopeful for temperatures here on land.) And it is not all or nothing – any emissions reductions will help, so the failure to act in the past is not an excuse to continue to fail to act.
  • JULY: Maybe we could replace congress with AI agents working tirelessly on behalf of us voters. Or maybe we could just have AI agents tirelessly paying attention to what the humans we have elected are doing, and communicating in both directions.
  • AUGUST: I did some musing about electric vehicles in August. The hype bubble seems to have burst a bit, as they did not explode onto the international commercial scene as some were hoping/predicting. This is partly because public infrastructure has not kept pace with the private sector due to sheer inertia, but I always detect a whiff of the evil oil/car industry propaganda and political capture behind the scenes. Nonetheless, just as I see happening with computer-driven vehicles, the technology and market will continue to develop after the hype bubble bursts. In a way, this almost starts the clock (5-10-20 years?) for when we can expect the actual commercial transition to occur. It will happen gradually, and one day we will just shrug, accept it, assume we knew it was coming all along, and eventually forget it was any other way. And since I seem to have transportation on the brain, here is a bonus link to my article on high speed trains.
  • SEPTEMBER: Countries around the world update their constitutions about every 20 years on average. They have organized, legal processes for doing this spelled out in the constitutions themselves. The U.S. constitution is considered the world’s most difficult constitution to update and modernize.
  • OCTOBER: Some explanations proposed for the very high cost of building infrastructure in the U.S. are (1) lack of competition in the construction industry and (2) political fragmentation leading to many relatively small agencies doing many relatively small projects. Some logical solutions then are to encourage the formation of more firms in the U.S., allow foreign firms and foreign workers to compete (hardly consistent with the current political climate!), and consolidate projects into a smaller number of much larger ones where economies of scale can be realized. There is some tension though between scale and competition, because the larger and more complex a project gets, the fewer bidders it will tend to attract who are willing to take the risk.
  • NOVEMBER: You can charge moving electric vehicles using charging coils embedded in roads.
  • DECEMBER: Bill Gates recommended The Coming Wave as the best recent book to understand the unfolding and intertwined AI and biotechnology revolution. I also listed the 2024 Nobel prizes, which largely had to do with AI and biotechnology.

Synthesis

Nuclear weapons and hypersonic missiles. The massive silver lining here is that, as I write this, there has been no use of nuclear weapons in war since 1945. Let’s hope it stays that way, forever and ever. But the expansion of nuclear arsenals among the existing powers, the open discussion of proliferation to new state actors, and the erosion of treaties and taboos on use of nuclear weapons are all deeply concerning. I find the hypersonic missiles particularly disturbing. These are being used in active, hot wars between nuclear powers – between Russia and NATO’s proxy Ukraine, and between Israel and Iran. We also hear that China has developed these weapons. Missiles are scary to begin with, but what is very, very scary is that these seem to be nuclear capable missiles and they are being actively used in hot wars between nuclear powers right now. If there are only a few minutes of warning when they are incoming, and they effectively can’t be pre-empted or intercepted, how does anyone know for sure that they are not nuclear armed before they hit their targets? So far, it seems like all sides are waiting for missiles to hit before we confirm they are not nuclear missiles. What if a state actor decides they can’t afford to wait and see and considers a pre-emptive strike? China and Iran have no-first-strike policies. The United States does not, and here is a fun fact – the SOVIET UNION had a no-first-strike policy, but modern Russia does not. Just to heap a little more sunshine on this topic, the rapid collapse of Syria, an aspiring nuclear power at one point, made me wonder if something similar could happen in Pakistan. And there is always the prospect of nuclear terrorism, particularly frightening when combined with extremist ideologies that glorify suicide and mass killing of civilians. It is easy to imagine horrible scenarios for all mankind on this one – but again, it is a risk that hasn’t materialized and can be managed. And it actually seems like a simpler, more tractable problem to me than complicated scenarios like climate change. Nuclear weapons are in the hands of relatively few leaders, and there is plenty of precedent for what arms control treaties and risk reduction measures can look like. Courageous leaders can step up on this issue – where are you guys?

Climate change. Let’s continue my little happy pep talk on existential threats. The climate change crisis is biting our civilization right now, and not only that, we are in the middle of it, not the beginning, and it is accelerating every day. This is the physical and socioeconomic reality, while our human civilization’s perception of reality let alone willingness and ability to act lag far behind. This is starting to feel like a story that will not and cannot end well. It is starting to bite our cities in the form of floods and fires, and this is well before relentless sea level rise really starts to bite in a significant way. Another place it will gradually start to bite harder, if it has not already, is food prices and eventually the physical food supply. As much as we have whined about food prices here in the U.S., the rise has been much worse in developing countries. And everything I just said is about the slow, steady, but relentless changes in the climate we have been experiencing and have to expect we will keep experiencing, at a minimum. The small piece of good news here is that if we took action immediately, we would start to see improvement in the trends immediately, rather than having to wait for some lag period to pass. My understanding of this has changed in the past year, and this is something positive. BUT what if rapid, sudden changes are in store? Some of the most terrifying articles I highlighted in 2024 have to do with tipping points, also known as runaway trains. We know about the accelerating melting glaciers and ice sheets, and how a sudden collapse of ice could lead to catastrophic and sudden sea level rise. We are seeing sudden rises in atmospheric methane concentrations – there seems to be some chance that this is the beginning of a feedback loop where frozen soil and seafloor sediments release methane bubbles as they thaw, which leads to more warming, which leads to more thawing, which leads to more warming and so on in a catastrophic exponential feedback loop that can’t be stopped on any time scale meaningful to humans. I hope we are not looking back a few years from now and concluding 2024 was the year that kicked this off. Now for some very small positive words – no matter how long our human political leaders dither and delay and fail, it is never too late to take actions that will make the outcome less bad than it could have been. Think about the reverse – if you were going to purposely try to make the situation as bad a possible, you could do things that would make it worse (like take all energy production back to coal). So past failure is never an excuse to stop trying, it is truly never too late to do better, even if our lack of effective action to date has closed off certain positive outcomes forever.

Bird flu. Continuing the doom and gloom theme, a major pandemic with a high mortality rate is clearly another existential threat we face. It could come from a natural source, a laboratory accident, or an intentional act. The risk of the latter will grow as biotechnology continues to progress and, unlike nuclear weapons, becomes more accessible to the masses. It’s like a major flood or earthquake. It will happen sooner or later. There are things we can do to limit the damage and to recover more quickly when it does happen, and we are probably not doing enough. The current strain of bird flu is concerning as it continues to devastate wild and domestic birds around the world, has spread extensively to domestic cows, there are some reports it has spread to pigs, and it has spread to some humans supposedly through direct contact with animals. Now having said all that, 2025 is probably not the year we get a devastating pandemic flu. Every year is probably not the year, because this is a low probability event in any given year that becomes highly probable over a long period of time. So the thing to do is stay calm and prepare. I actually have some hope that the vaccine technology that was rapidly scaled up and commercialized during Covid-19 will help us when the pandemic flu does hit. Let’s hope it’s not this year or any time during the next four years when we cannot expect to have competent leadership in the United States.

Artificial Intelligence. I suppose I have to say something about it. Well, I can’t recall in my lifetime any technology exploding exponentially into widespread commercial and public use in just over a year from its first announcement. You could almost describe it as…a singularity? Well not quite, but an ongoing exponential growth with no end in site, which is how a singularity would begin. Now, the downside is the sudden, massive, and completely unexpected energy demand this is causing, to the point that recently retired nuclear plants are being turned back on. I joked that AI might be the explanation for the Fermi paradox, where every civilization in the cosmos advanced enough to develop this technology wipes itself out by fouling its own nest when it tries to generate the energy required. I don’t believe this though – given that it’s easy to imagine an alternate history where nuclear fission based energy was scaled up in a serious way, and/or space based solar energy was scaled up in a serious way, and fusion based energy looking at least somewhat plausible, it does not seem like a foregone conclusion that we humans here on Earth had to foul our nest. This does not mean there is hope for us, it just means that there might be hope in a galaxy far, far away or in a billion of them too far away for us to see.

AI Agents. Now, as we foul our nest over the next few decades, there is the question of where AI goes in the next few months and years. And one big thing, I think, that is going to change our lives pretty quick is AI agents. We don’t really have AI going out and actively engaging in communications and transactions on our behalf on a large scale yet. But this has to be happening behind the scenes, and it has to happen in an obvious public way pretty soon. Imagine if I asked an AI to keep track of what one of my elected representatives is doing each day, read and summarize legislation they vote for or against, and just explain it to me in an easily digestible way for five minutes a day. Now imagine my AI is talking to my representative’s AI, and everyone else’s AIs are doing that, and giving the AI a summary of what all these AIs are thinking. That sounds pretty democratic right? But now imagine AIs from companies and governments are trying to manipulate all of us to buy things and believe things and do things they want us to do. Now imagine ALL THESE AIs ARE TALKING AND TRANSACTING WITH EACH OTHER, ALL THE TIME, AND THEY NEVER GET TIRED OR NEED A BREAK. It gets dizzying pretty quick.

Competing Feedback Loops. AI has definitely increased my personal productivity in writing computer programs and communicating the results in the past year. This must be happening on a large scale, at least it certain types of jobs. On the other hand, the IMF tells us worldwide productivity has slowed down since the 2009 financial crisis and was made worse by the Covid-19 crisis. There are also continuing headwinds like aging populations and falling fertility rates in many developed countries. How can both these things be true, an acceleration of productivity and a slowdown of productivity? The way I think about it, they are competing feedback loops, kind of like the faucet in your bathtub being on while at the same time there is no drain plug. Whether your tub is filling up or draining down depends on the relative strength of the positive and negative feedback loops. And unlike your bathtub, both are changing in time and subject to random shocks. So it could go either way – civilization could be going down the drain, the technological singularity might be imminent, or the two could be close to balance so it seems like nothing is happening for a long time, until one of them gets the upper hand. These are not the only feedback loops of course – the ongoing climate and biodiversity crises are also in the mix and since these are negative, we have to really hope that AI faucet is wide open, or find a stopper for the drain, or some combination of the two. We don’t have many world leaders working on the stopper thing right now, many are trying to drill baby drill an even bigger hole.

Biotechnology. AI seems likely to accelerate the progress of biotechnology, leading toward both medical breakthroughs (universal vaccines, cures for cancer and diabetes) and increasing risks of accidents and terrorism. Its hard to predict when these things will hit the news – progress is slow and steady for a long time, and then a technology will seem to burst onto the public scene all at once. Sometimes there is a big hype bubble that reaches a peak and seems to explode, and then while the public assumes the technology is dead, the slow and steady progress toward widespread commercialization resumes and eventually takes hold of the entire system. And then we shrug, forget the past, and assume we knew it was coming all along.

Electric Vehicles and Autonomous Vehicles. The U.S. government might be throwing up some headwinds to technological progress (i.e., doing their best to usher in a dark age not a “golden age”), but the global socioeconomic and scientific systems that drive technological progress are much too big to be constrained by the U.S. government. While many in the U.S. may have the impression that the electric vehicle revolution has stalled, it is forging ahead in Asia and around the world. China is building cars for $10,000, and nobody else (Japan, Korea, or Tesla let alone Detroit) can figure out how to compete with this. I suspect one driver of the protectionist impulse in the U.S. is fear that we have no chance of competing, so our government is willing to imprison us in a bubble of outdated technology at uncompetitive prices, and if they can’t outright restrict information about the outside world from getting in, they will use propaganda to distort that information so we don’t understand what we are missing. It’s like the Soviet Union, or worse, North Korea. We are certainly not as far behind as the Soviet Union or North Korea relative to our peers yet, but this is the path we are headed down. Similarly to electric vehicles, we are hearing from our media that autonomous vehicle technology has stalled or under-delivered or is risky (it’s not, by any rational measure compared to the massive death and suffering caused by human-driven vehicles). But this technology has in fact arrived, just arrived unevenly in certain cities in the U.S. and around the world, and our government policy is slowing its spread for example with policies that do not allow autonomous vehicles on highways. These two technologies – electric and autonomous vehicles – have to combine and reinforce each other sooner or later, and this will change a lot of things about how our cities and infrastructure are configured in the future. It’s hard to give a timetable, but I bet if you go to a leading edge city in China, Korea, or Japan a decade from now these technologies will be everywhere and it will seem like science fiction to a U.S. traveler who has been kept in the dark about the state of the outside world as our once world-leading country has stagnated.

Inequality and the Wealth Pump. I hadn’t heard the term “wealth pump” before reading Peter Turchin in 2024, but it rings true. Wealth and income inequality is just the elephant in the room behind the 2024 U.S. election and many other geopolitical trends around the world. It is getting worse in the U.S., and it is not going to get better as long as the wealthy and powerful are able to continue rigging the rules of the system more and more in their favor. The pain of the masses is very real. And Donald Trump may have found rhetoric that taps into this pain, but his administration is certainly not going to make the situation better. But nor has the Democratic Party shown any signs of making the situation better. They may tinker with some marginal policy changes that slow the trend (for example, the short-lived increase in tax credits to offset childcare expenses, some steps to slow the rise of prescription drug prices) but do not reverse it (for example, creating real childcare, education, and health care benefits that reach the vast majority of working citizens). Bernie Sanders is the only U.S. politician who has spoken authentically to the people about these issues in recent memory, and he reached a lot of people although not quite enough when the established Democratic Party did everything they could to sabotage him. There is also the problem of half a century of very effective anti-tax propaganda that is very hard to overcome. But still, I believe Bernie showed us the way. The Democrats need to embrace the man and his policies, and find him a true protege or several to choose from who are able to speak with his authenticity and maybe a bit more youth and charisma. Trump is all but guaranteed to fuck up massively over the next four years, so the question is will the Democrats let his propaganda machine convince us to blame scapegoats or will they be ready?

Government of the Fools, By the Fools, For the Fools, and Where’s Waldo? Before January 20, 2025 it was clear to me that the U.S. will be governed by fools and amateurs for the next four years. And this alone is sad because it will lead to our continued stagnation and at least relative decline while peer countries are moving into the future. It is also dangerous because the nation might be able to muddle through while there is nothing unusual going on, but fools, amateurs and clowns are not going to prepare or respond effectively to emergencies, disasters, and unexpected events. Four years is a long enough time that some unexpected events should be expected. We can only hope they are not too far out in the tails. But as I write this on January 23, 2025, it seems even worse. Trump is a fool, but a very powerful and dangerous fool, and at least some of the people whispering in his ear are evil cruel-hearted psychopaths, sadists, and outright devils. I don’t think Trump is Hitler, because Hitler believed in things (evil, twisted things) whereas I think Trump is a pure psychopath who believes in nothing and is willing to say or do anything he thinks will increase his own power. But who are the Heydrichs, Himmlers, and Goebbels among his supporters? I am not sure, but whoever they are they are hiding in plain site in a crowd of clowns and fools where they are hard to pick out. It’s time to play a little Where’s Waldo.

Welcome to 2025!

And that is all the sunshine and light I have to offer you here in this January 2025. If you are a human being reading this in close to real time, happy 2025 and may it be better than expected, which is not a high bar at all! If you are an alien archaeologist reading this in the far future, I hope it helps you make sense of the rubble of our civilization. If you are a transhuman reading it after the singularity in the near future (I heard October 2029 according to Ray Kurzweil’s latest prediction?), I hope you are laughing that the problems that seemed so dire to me in January 2025 had solutions just around the corner!

Planetizen’s top posts of 2024

There are a lot here. Quite a few have to do with housing, a topic I would be interested in brushing up on. A lot have to do with transportation, a topic I have just feeling complete and utter despair about, at least in the context of the United States and my particular city and state. One possible bright spot is congestion pricing in New York City. Congestion pricing just works, even though it is politically unpopular and counter-intuitive to many people’s “common sense”. Maybe people will notice that it solves some of the congestion and parking issues they like to complain about, and maybe it will slowly spread to other cities and states.

top urban planning books of 2024

I always enjoy Planetizen’s list of top urban planning books. My training is in engineering, but like almost everyone I am a citizen of an urban area, and besides urban planning is an umbrella that touches on many aspects of engineering, infrastructure, housing, the economy and the environment. Anyway, here are a handful of books that caught my eye. My commentary below doesn’t really have much to do with the books (which I haven’t read), but rather my off-the-cuff thoughts on the topics each book is nominally about.

  • Key to the City: How Zoning Shapes Our World by Sara Bronin – The tide of opinion seems to be against zoning at the moment, but it is just such a basic and important tool to try to shape the types of human settlements we want to live in, and that could be different for different groups of people. I think of private zoning and building codes as one half of the coin, and public infrastructure as the other, but I haven’t really seen a book that gives them an even treatment. Someone should write that book – maybe me, some day somehow?
  • Free the Land: How We Can Fight Poverty and Climate Chaos by Audrea Lim. “No piece of ground goes untouched, whether it’s private property, a public right of way, or government-owned open space.” Okay, maybe this one actually attempts something along the lines of what I mention above.
  • A Paradise of Small Houses: The Evolution, Devolution, and Potential Rebirth of Urban Housing by Max Podemski. Because I don’t really have a coherent personal theory of what is wrong with housing and the housing market in the U.S., but there is obviously a lot wrong and I would like to smarten up on this some day. But it pretty much seems to come down to needing more supply of housing whose market value matches the economic means of the majority of households, whereas there is a mismatch currently. Zoning is part of the problem. High rise living and public transportation could solve the problem if we wanted it to, but we just don’t seem to want that. Row houses and town houses with small porches, backyards, roof decks, and corner stores are a compromise in my view – these offer people more privacy and private outdoor space while allowing a pretty dense urban fabric to develop. But you just can’t mix this with universal private car ownership people, because geometry. Maybe autonomous vehicles will be the killer app that could eventually break this logjam, because they can move around in a more space-efficient way and go store themselves in out of the way places when they are not in use, which is most of them most of the time.
  • The 15-Minute City: A Solution to Save Our Time and Our Planet and Shrink The City: The 15-Minute Urban Experiment and the Cities of the Future. Relevant to the above. Basically a new(ish) way of explaining some of the concepts I mention above. I don’t think these ideas have penetrated the endlessly ignorant public discourse on “traffic” and “parking” just yet. Or is the problem just that geometry is not taught in a way that people relate to the actual physical universe?
  • On the Move: The Overheating Earth and the Uprooting of America by Abrahm Lustgarten. Right, so where are we supposed to live again? Of course, I want to sell my coastal property just before the real estate market wakes up to the fact that it is doomed – when is this? It also occurs to me that we better consider “the Americas” here and not just “the United States of”.
  • Radical Adaptation: Transforming Cities for a Climate Changed World by Brian Stone, Jr. Sounds a bit more technical than the one above. Please, let’s not turn everywhere into Singapore, which is essentially a network of air conditioned malls, offices and high rise housing connected by subway tubes. But you could pretty much build Singapore on Mars, or wherever, as long as you have some plan to get food and water to the people there (but this might be tricky in a “climate changed world”, eh?)
  • The Stadium: An American History of Politics, Protest, and Play by Frank Andre Guridy. The only reason I would read this one is that Philadelphia has been embroiled in a debate about whether to build a downtown basketball and hockey arena, and I would like to be a bit more informed on the issue. I walked by the one in Washington, D.C. the other week and it seemed to fit into the city fabric okay to me. Then again, what New York and Washington do well, Philadelphia has a tendency to do in a half-assed amateurish less good way about a decade later. And when we fail to implement proven solutions competently, we conclude that the solutions themselves were unworkable from the start.
  • Lost Subways of North America: A Cartographic Guide to the Past, Present, and What Might Have Been by Jake Berman. Speaking of Philadelphia, we have such a phantom system, including some stations that were built in anticipation of train lines that never actually got built. Thinking big is also no longer a thing, which is sad.
  • Human Transit: How Clearer Thinking about Public Transit Can Enrich Our Communities and Our Lives by Jarrett Walker. This is an update to an earlier book I haven’t read but would like to. Is this the book that all high school students or at least all undergraduate engineering and architecture students should read to have some basic literacy about transportation? Otherwise our mistaken ideas about how a functional transportation system could actually work will allow the auto-oil-highway-suburban sprawl propaganda machine uncontested dominance over our society and our land forever.
  • Killed by a Traffic Engineer: Shattering the Delusion that Science Underlies our Transportation System by Wes Marshall. Slightly unfair to blame the engineering profession alone for the evil auto-oil-highway-suburban sprawl monster I mention above, but some fair points here nonetheless. If you read the American Society of Civil Engineers code of ethics for example, you might think we would stand up to some of this rather than be the nails the monster uses to hammer the lid on our society. But we would have to wake up to the fact that the propaganda exists and is controlling our minds first, then pull the tubes out of our asses and get flushed out of the matrix before we could go to work.

If I sound a little bit salty when I think about transportation design, (lack of) maintenance and enforcement, and reckless driving and lack of respect for human life up and down our society, yeah I’m a bit salty!

why “free-flow” car sharing isn’t working in the U.S.

This article describes several attempts to create “free flow” car sharing services, where you can pick up and leave a car anywhere within a certain zone. This is in contrast to Zipcar’s “fixed model” where you have to leave the car where you found it. The article says the free flow model isn’t working well because the people it benefits most are lower-income people who do not otherwise have easy access to private or public transportation. But this market just does not have enough demand to cover the cost. This model is working well outside the U.S., and the article suggests one reason it does not work in the U.S. is the massive subsidies we have in place for private vehicle ownership with massive public funding for roads and parking. The car-highway-oil-sprawl industry propaganda is so entrenched that we can’t see these massive subsidies hidden in plain site. Take your red pills, people!

In October I passed the “car ownership free for 20 years” mark, which I am very proud of. I made it to the milestone through the stroller and car seat years, which was sometimes difficult. But I will say I have a Zipcar membership which I rarely use, and there are really two reasons. First is living in a walkable, public transportation oriented community. I simply don’t need a car most of the time, and I suspect the people who might currently be interested in car sharing are also the ones who value public transportation. But second, ride hailing has just gotten so convenient and it is much cheaper compared to Zipcar, so I really only use Zipcar if I am hauling something. It occurs to me that once cars can drive themselves (okay, they can now, but once the various institutional/legal/policy barriers are sorted) there will be less distinction between the two models, and car sharing will eventually go away. Public agencies can subsidize ride hailing if they want to, and I am actually concerned this will put downward pressure on the demand for traditional public transportation (buses, trains) and lead to doubling down on our poor low-density land use choices.
