OK, forget my dumb last comment... So imagine... cars are automated, and possibly pooled. Bus is the most energy efficient way of transport. So you want to go from A to B. Instead of looking up static train/bus schedules, you just type that into your phone. A server system looks at how many people wants to do a similar trip, and automatically starts an automated taxi that would have just the needed size and will come up 10/15 min later. That way you get the best of both worlds. And if that's not enough space privacy for some, you could just plug mini-cars together, eliminating air resistance but with everyone having its close module transport. Even better, you could switch module transports between road trains. The possibilities are unthinkable. I think this marks the beginning of a new ear in transport.
