As much as I want it to happen, and as much as I agree with you that in the near future is going to happen, I think you are missing the context. You seem to be forgetting we already have cars. Not only that, we already have planes, bullet trains, spaceships, etc. We even have the bicycle; transport has been "free" for a long time. The only thing equivalent to the steam engine in impact would be teleportation. That is the jump from the horse to a train, or from a train to an airplane. Self driving cars are cool, they are not steam-engine-in-the-1800s cool.
