Roads are something we all own and have a right to. So it hope it remains possible to manually drive a car on them, if for no other reason than for transportation during emergencies.
However, everyone here seems to assume that an auto-car has a driver in the driver's seat. Why exactly?
In my auto car I will turn the driver's seat around and talk to people. Or I'll sit in the passenger seat so I have lap room to do some work on the way to work. I may not even be in it. My car will drop me off at the front door of my office. I don't care where it parks. It can go fill up or charge somewhere far away from my office. It can go run errands for me to pick up stuff I bought online and/or rent itself out to make deliveries or taxi for awhile.
In fact, we may have destroyed the mass market for individual car ownership.
