> Even substantially expanded rail will never solve the problem of "I want to get from point A to point B, as quickly as possible, whenever I'm ready to leave" in a fundamentally different way. But a substantially improved autonomous car driving experience - with cars communicating with each other (actively or passively) to avoid congestion, avoiding parking needs by being on the move always and increasing "bandwidth" by driving close to there other cars and still being safe - may look like railroads on all our roads. Bringing both these worlds closer to each other.
