A useful public transportation system build out in a America is more ambitions than fully autonomous driving. Human-less driving is more of a technical problem than can probably be overcome with research, 10s or 100s of billions worth of development and municipal cooperation on autonomous driving infrastructure.
Public transport is a cultural problem as well as a technical problem. I live in a city with decent public transportation system options. I use it frequently and I'm grateful for it. But as soon as I go even a few miles outside the city, the public transportation options are slim to non-existent. I wouldn't even pretend for a second it's a practical option. You better have a car.
