Not if it works the way Google intends. In theory, the autonomous car couldcan drive on any street, in any condition in America. The only real infrastructure change that would be needed would be a dedicated a drop off and load lane at the parks and that is simply for efficiency. They could just as easily park in the parking lots, but that would require significantly more vehicles for it to work.I'm with you on that, but it would have to have its own grade separated pathway, blocked off to pedestrian and motor traffic.
