My vision is for the folks going to work, they will reserve their car that showed up on time each day and they take their 30 minute commute working on email etc. When work is over, they schedule another pickup and ride home. No need for a "work car".
The cars run themselves, recharge in parking garages no longer needed, and then turn out for service the next morning. And, they could operate within feet of each other and send telemetry to each other about conditions up ahead, and communicate with smart signals etc.
Retirees could call one to go shopping or to play golf or whatever, no parking to worry about.
