I'd be really hesitant to say anything involving humans and human judgement under uncertainty is trivial. What if the customer wants the car to drive aggressively, maybe speed a little where it "seems" safe? Should the car stop for an object that might be a plastic bag or a child's backpack? Even manual drivers are difficult to "verify" because accidents and traffic violations depend on interpretations of events, which is why we often have to go to court.
