Another thing that's going to take a huge it is police departments. Many of the initial encounters with police are by way of a traffic stop and patrol. With a self-driving car, there's no longer "probable cause" because the car is driving itself. This will cut off a huge source of income from the police and at the same time reduce the need to have so many police, which, in my mind, is a good thing. Expect entire highway patrol and regional agencies to be shuttered.
