I'd like to hear the law say that self-driving cars should collect data (video, sensor inputs, actuator outputs), and that it is the property of the law when an accident happens. No exceptions. The real question is how the law is written, for it should leave no doubt about what Tesla, or any other, is required to do. Probably all cars should have a black box, as both modern electronics and humans can do weird stuff.
