i’m arguing that this is not a chicken or egg situation because the costs involved to bring that chicken to life (especially when starting today - at least the 19th-century head start NYC got allowed them to build quick and cheap!) would be so high that your farm is going to be bankrupt before anybody lays any eggs.
Pick a US city, then pick a neighborhood within that city you feel is emblematic of the pattern you observe. We've selected a few -- Seattle, Minneapolis -- go ahead and you pick one where a US city would not be able to support it. Then we can look at that example together.
Local. Because of all the stops buses average 25 mph. Long runs, this adds up considerably. It can't be fixed without a lot more buses and a lot fewer stops.
Shanghai. Buses stop much less frequently. More walking, but a bus is not that much slower than a car. And the subway doesn't have traffic jams, long runs you'll almost always get there faster with walking/subway than by car. There is also a climate factor--they get more rain but much fewer extreme days.
