Right. So the question is, at what point do we start turning auto-autos (I should use that word) loose on the road for live testing? Do we have to wait until they are demonstrably better than human drivers? How do we prove that? After reading the Atlantic's Waymo article, I'm more convinced that Uber is doomed in this race. They're not investing properly in simulation, and Waymo is getting an enormous amount of programming done based on controlled simulations that Uber isn't - billions of miles, and repeatable scenarios. Tesla is really in the game, I think, because they're able to collect so much data from the AutoPilot systems currently on the road, even if they're not in use. They still get all the telemetry for complex real-world situations. But at some point, you have to let experimental software out on the road, to learn from the real world. Simulation is insufficient. Or, we simply refuse to allow auto-autos at all, permanently establishing that humans will always be more capable, without evidence. So it's a question of when, not if. There's a couple of currents going in the arguments here. Some say "not yet", and some say "never". I think the "never" people are nuts. Auto-autos that broadly outperform human drivers safety-wise seems achievable to me in the not-too-distant future.
