Arlington, Texas is an illustrious example. Almost 400k people and it has nothing.

Interesting. Thanks for the example.

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.
