Good point, plus if everybody had autonomous driving, then the software should prevent anyone from cutting people off. I can also see a world where platooning is possible (instead of the first car leaving the stop light, then the second, then the third… because it takes a moment for people to notice, everyone accelerates at the same time in formation. We could also be driving down the highways packed like a nascar race at Daytona and when a car needs to exit, the platoon parts like the Red Sea to let the exiting car leave the platoon. It might be scary to us to all be inches from each other, but then traffic jams in big cities would never occur in this scenario, except for the occasional broken down car. Even then the other vehicles could choreograph the lane changes to avoid the normal jam up.
of course, people’s freedom to express themselves like the coal rollers would be banned. No more drag racing. And cars with fast 0-60 times would be completely useless.
