Elon Musk loves to boast about how safe Tesla’s Autopilot is. There are two statistics he often cites. The first is a supposed finding by the National Highway Traffic Safety Administration (NHTSA) that Autopilot reduces crash rates by 40%. The second is that Autopilot is 3.7 times less likely to be involved in a fatal accident than the average car.

The 40% crash rate reduction statistic was already debunked earlier this year when the NHTSA said it was derived from Tesla airbag deployment data, not Autopilot safety assessments. In this article, I will show why the 3.7 times safer statistic is also flawed.
