Here are just a few thoughts:
- Rental cars — for simple one- or two-day rentals, why go to Hertz or Avis, when you can just use a car-on-demand service? Will they also get into the car "as a service" business? They'd better or they will go the way of the horse and buggy.
- When you have an autonomous car, how does it work when you cross state lines and the regulations are different?
- For police investigating an accident where an autonomous car was part of the crash, what data might they be able to get from the car to understand what happened?
- Can you be blind and "drive" in an autonomous car?
- Can you be drunk and in charge of an autonomous car — because you are not driving?
- When you reach the Canadian border with an autonomous car, will you be allowed entrance to the country and likewise, the United States?
- You can take the "suicide" aspect out of car bombs.
- How does a "drive by shooting" change?
- In a car chase, might the police be able to "shut down" the autonomous car to make it stop?
- Will you need a driver's license for an autonomous car?
- What age will you have to be in order to be the sole rider in an autonomous car?
