Tesla said it recorded one accident for every 2.91 million miles driven in autopilot during the last quarter of 2018.

What is the human crash rate per 3 million miles driven?


According to NHTSA, it was about 2.3[0] accidents per million miles driven in 2016, or one accident per 0.43 million miles. However, you probably shouldn't directly compare those numbers without at least separating highway miles from surface streets, as Autopilot-enabled miles driven may have a very different profile than the national average in this regard (I'm not familiar with how Autopilot is used in practice).

Ugh.
