> Why would the car have to wait around in the parking lot all day while you're at work? It could easily keep running around ferrying people places.
Yes those are called buses and taxis. :) they already exist. they're dirty. and they're not always available when you need them.
One advantage to what you're proposing though is that unlike buses and trains you wouldn't have to put up with dirty, dangerous or rude people near you in the same vehicle.
Why would there need to be other people in the car? It would most likely work just like cabs, but without a driver. You tap a button on your mobile and a car pulls up already knowing where you are going.
