In rural America their often is no bus.

In the city I grew up in they had no busses until a local company paid for the first one simply to get the poorer employees to work reliably because it was impacting production.

There are still many places in America where you either walk or you own a car, period. When the car breaks down and you need parts.. you walk. Worse there are no sidewalks. When the snow is a foot deep you risk frostbite and hypothermia.
