But you can't predict what would happen. Driving even healthy and sober, something could happen. Assuming you're in a more developed version of the self-driving cars, machine-learning has most likely come a long way since the beginning. The car/network of cars would have learned by now that the command: "Stay on the right side of the road." Doesn't mean to stay on the right side of the road but it's okay to hit a few cars or pedestrians." They would have learned, or have programmed in them, that hitting cars or people is not good. Machines don't have a moral sense, and hoping that they are not completely sentient, this means that they don't have opinions, meaning that if you don't like this guy, you can be a little rude to him. And my last point is that the network of cars, all communicating at once, would learn how to be safest. Done.
