Here come the package delivery robots. I don’t know that this couldn’t work in a quieter urban residential neighborhood. This would work great on several narrow streets I have lived on in Philadelphia, where post office and UPS/FedEx trucks typically double park at the nearest intersection (often blocking crosswalks, fire hydrants, bike lanes, etc. because there aren’t other options) and then walk in. Urban areas can take a number of forms other than high rise towers and central business districts, which is what (most likely suburban living) authors of articles like this always seem to be picturing.
