Not to mention the fact that non-autonomous cars will continue to exist en-masse. People value the experience of driving a car (especially sports cars or classic cars, but even just the every day sedan) and I don't think that the advent of autonomous cars will eliminate that for a very, very long time.
Unfortunately you are probably right with that, especially in the US where people value individual freedom over pretty much anything else. I expect Japan and China to be first with having meat driven cars and the US and Germany to ban them last. Not banning them will come with a tremendous economic cost.
