>In the US even multi hundred thousand people cities have literally nothing other than cars as an option.
I'd be interested in hearing an example or two of cities in the U.S. with populations greater than 200,000 that don't have a bus system.
Arlington, Texas is an illustrious example. Almost 400k people and it has nothing.
There is also a distinction between "has a bus system" and "the bus system is actually usuable". Say you want to take the bus to jury duty, but calculate that you would need to wake up at something like three in the morning to catch the so-and-so to downtown, and then another bus out to where the jury place is (trip time: multiple hours, assuming all goes well), in addition to the usual playing Frogger across a stroad or two, or even more walking to maybe find legal road crossing facilities for humans, assuming they exist. And that was in a city with a relatively good (for America) bus system.
