Re: The elephant in the back seat
So how does 5 crashes and 2 fatalities in approx 3 years and god-knows-many-miles since deployment compare with human-driven cars.
Depending on which report you read the exact figure varies, but they all seem to be around 1 billion miles of cumulative Autopilot, and around 10 billion Tesla fleet miles in all modes.

And according to OECD IRTAD data for 2017, road casualties in the US are 7.0 deaths per billion vehicle km.
Tesla Autopilot: 2 deaths per billion miles
US average: 11.2 deaths per billion miles
So at crude face value it looks like Tesla's doing well, except that's not adjusted for vehicle type and driver population, nor for the fact that Autopilot is something you'd engage on the open road. All of which I'd expect to bring the US average figure down dramatically, perhaps by a factor or 3-4, based largely on UK experience that shows that major non-urban roads are significantly safer per vehicle mile than urban and minor roads.
Overall, I don't think the evidence strongly points one way or the other when measuring fatalities per vehicle mile.
