If I were to guess, once self-driving cars are widespread, cars won't be pulled over any more for driving-related issues (ie, cops won't radar any more). However, they will probably be required to have a kill switch that can pull it over for other reasons (ie, if the cops thought your car was the getaway vehicle from a bank robbery)

This is of course once almost all cars are self-driving so it'll be interesting to see what happens in the midterm.
