Distances in a lot of the US (I live in Texas) are such that I don't see cars disappearing. What might happen is more short-term renting of cars. But a lot of American cities were built around the automobile, so they would need a lot of changes to function in a post-automobile world. That makes such a transition much less likely. I think it would work better in older, East Coast and mid-western cities that largely predate the automobile.
