Comment Depends whether it has manual override. (Score 1) 301
If the car has a way to let the passenger take manual control and override the autopilot, then the passenger has become a driver and should be properly licensed.
While I don't discuss the licensing issues, my book The Reticuli Deception (set about 100 years from now) has several scenes involving both completely autonomous (sole occupant darkens the windows and takes a nap) and not (driver overrides the computer to deliberately cause a collision with the guy tailing someone, then escapes by having arranged for a rental car to drive itself to the next block and be waiting for him). (That's only a minor spoiler, most of the book takes place off-Earth. Caveat, it's a sequel to The Chara Talisman, which come to think of it has one scene with an autonomous taxi.) </blatantplug>
