Realistically, I don’t see how anyone could EVER pass a law saying humans can’t drive where other cars can. Americans (I’m one!) seem far too independently minded, in the sense of wanting to be in control themselves.
Even if you could get 90% on board, the other 10% will fight to the death over it.
Which means the benefits of a 100% automated system (which I disagree with BTW), can’t be reached except possibly after a VERY long time when enough anti-robos have changed their minds/died out.
Highways didn’t exist when cars became common. They came because of cars. We never took them away from horse riders. We gave car drivers a new option.
This would be taking something away from drivers. And that’s what people hate. Look at the responses to congestion taxes or toll roads. Or even traffic jams!
People behave as if they have a right to use any (seemingly) public road just because they have a car. Even private toll roads.
