We need independent numbers on this. Comparing with the same population, the same price range of vehicles, the same road sections. Age, level of education, price of the vehicle, absence of hands-free cell interface, lack of seat-belt alarm seem to be way better predictors in USA of fatalities than having autopilot.
Comparing autopilot Tesla fatalities versus average fatality rate on one road section is dishonest.
It's not as precise as I'd like, but there has been an independent investigation of the safety of Autopilot. After the first fatality while on Autopilot, the US National Highway Traffic Safety Administration wanted to determine whether (as many fear) Autopilot posed a danger to drivers, and found that Autopilot was safe enough to keep on the roads and that Autopilot led to a 40% reduction in crashes: https://techcrunch.com/2017/01/19/nhtsas-full-final-investig...
