* Generally newer than average.
* Generally owned by more affluent drivers than average.
* Probably used predominantly in urban areas instead of rural ones (to be clear this might unfairly tilt the stats against Tesla thanks to the highway thing).
I'm not sure I've seen a good "apples to apples" comparison on this that corrects for these confounding factors.
It's also entirely self-reported, which given that they've knowingly lied about range, is itself a bit concerning... https://www.reuters.com/investigates/special-report/tesla-ba...
People look at their phones while driving with and without autopilot.
If we had better aggregate stats we could compute the statistical likelihood of it, but this stuff isn't tracked anywhere near as closely or completely as, say, aircraft accidents. I don't trust Tesla's self-reported cherry-picked stats.
(edit) I see that the article included that FSD is 5x safer than humans, which may be valid.
The article then said : "However, the only reason it is safer than the US average is that it is supervised by drivers who ideally pay extra attention when using FSD."
I am positive that they had zero data to back that assertion.
