I'd like to see a law that says: to obtain certification to operate a self-driving car on a roadway, an organization must agree to: 1) Conform to a standard set of protocols for how sensors provide data to a self-driving software system. 2) Log data in a form that could be submitted to any conforming self-driving software system, to obtain results from that system reporting what the system would do given these inputs. With this in place, it would be easy to do after-the-fact comparisons of data leading up to incidents, and learn from the differences in results between systems. It could be taken a step further if the car makers would also share data on near misses, which could uncover cases where other car makers' systems did not handle the situation as well. Even if the sensors are different, I suspect some good mileage could be gotten out of this. The fact that learning opportunities are not perfect, is not always a good reason to pass them up.
