Or simply people who don't like driving in traffic, its boring and annoying but you still have to pay attention and can't do much else except listen to a podcast or music. If the car drove itself you could work just as you can in a train or as a passenger. This would make a 1h commute much more tolerable. I can see many more people who don't want to drive deciding to use private autonomous vehicles over crowded/dirty public transit.
