The people living in true rural America truly do not have the ability to do so. But again, that’s less then a quarter of the populations and likely far less then a quarter of all kids.
Counterpoint: I lived in an extremely remote part of Vermont (population 400) for a couple years without a car, and I got around fine on my bike. The trick was living close to my work, which was easy since housing was dirt cheap. That said, getting out of town was difficult, as the buses (Greyhound) were notoriously unreliable. I also got random people buzzing me in pickups screaming at me for existing once in a while.
