Let’s assume your proposal — wires in the road to aid lane-keeping — works perfectly. What does it get us aside from lane-keeping? That’s far from the hardest problem. It doesn’t account for stopped vehicles, cyclists, pedestrians, deer, or any of the other things human drivers commonly encounter and avoid without fanfare. Even if we imagine some sort of car-utopia where only AV vehicles are allowed on your perfect roads it doesn’t account for common vehicle malfunctions like blown tires. You shouldn’t IMO scope the problem only to lane-keeping. That’s a very small part of the problem space. Solutions aimed at only that problem still leave the most important problems untouched.
