I guess, but I don’t see how you could square that with private vehicle ownership yeah? You’d have to replace all vehicles on the road, and even beyond that you’d need to completely clear the road of any obstacle. Bicycle? Gotta move. Trash can blown by the wind? Quick clear the road! To me this is why it’s a pipe dream. It’s so much effort for what upside? And then you lose the ability to drive yourself anywhere unless the computer allows it: that’s not fun either.
