I wish people would think of these more as self-driving _taxis_. And thus, cheaper taxis. Because most people that live in cities don't need a car all the time. An awful lot of people can use mass transit most of the time, and then a car occasionally. Turn that occasional car usage into a cheap self-driving taxi and you save on a lot of parking space.
