- The average US fatality is not in a ten year old car on a country road.
- US crash rates are lower than worldwide rates, so Tesla’s estimate of lives saved worldwide is low.
- If autopilot is only used part of the time, that implies its safety benefit is significantly more than 3.7x. A model S is not 3.7x better at passive safety than other cars.
Of course none of this data is very meaningful. You have to compare the rates of autopilot users to non-autopilot users of similar demographics, and have all crashes recorded, not just fatalities, to get close to a comparative samples.
> US crash rates are lower than worldwide rates, so Tesla’s estimate of lives saved worldwide is low.
Road fatalities per 100,000 inhabitants per year (2013, WHO):
UK 2.9
Spain 3.7
Germany 4.3
France 5.1
USA 10.6
Among the rich countries, the US crash rate is one of the worst. With a similar set of vehicles, this rate is very fluctuent, per country and per year. Hint: the problem may not be purely mechanical.
Seriously, would Tesla's autopilot lower the crash rate in the UK? In Thailand? I guess it wouldn't change much in European countries, and any good car would do the same in poor countries.
