I don't know. How often do you drive a car without having to worry about pedestrians, cyclists, stoplights or traffic laws? If I'm going to test an autonomous car, I'm going to do mimic real-world situations in my test environment.

Agreed. However, being able to isolate a large component of driving seems useful, too. It's like a unit test as opposed to an acceptance test.
