I'm not saying it has to be 100x better than a human. What I'm saying is, the averages today are across all vehicles on the road, some of which are old and have fairly low survival probability in an accident. And the deployment of technology to handle/avoid distracted driving is still in its infancy. If we just wait 10-15 years, I believe the safety rates for humans will increase by 10x over current US statistics. Then self-driving has to manage another 10x improvement over that, in order to be worth it.
