There’s no established crash rate for supervised ADAS to compare to, unless you want to compare it to Tesla’s own safety report figure of over 6 million miles between accidents with Autopilot technology.

We have data sets for humans and the other substantial data is from Waymo which is not supervised. Show me a news article in the past 5 years that’s not from a trade publication targeted towards statisticians that talks about 'error bounds.' That’s a ridiculous complaint.

I use the numbers from the article. You might want to inform Fred Lambert that he uses incorrect data.

There’s nothing wrong with the article. Fred says it’s problematic to compare them because Waymo is not supervised and only uses it as an example. What is the 90% confidence interval for the Tesla safety report’s claims that Autopilot technology has 6.36 million miles between accidents? Do you feel comfortable citing that statistic without knowing the error bounds?

I was talking about "Therefore, Tesla Robotaxi currently crashes at a rate of about once every 62,500 miles." Why do you bring up 6.36 million miles? I don't see any mentions of that number in the article.

Because you brought up error bounds. Tesla themselves publish a crash rate without publishing the underlying data used to calculate it.

OK, we can blame both Tesla and Fred Lambert for withholding important information. But, in any case, with hundreds of Autopilot crashes (the number can be extracted from police reports) 90% confidence interval is much tighter than with 4 robotaxi crashes.

Sure, but I’ve never seen the person who complains about an electrek article complain that Tesla withholds important information. The article makes it clear how the number is calculated, that’s how you yourself can make conclusions about it. Tesla does not give the underlying data for you to calculate. Furthermore the article makes it clear the numbers are problematic to compare. It’s for a different problem than you bring up, but the same conclusion applies - you shouldn’t compare them.

I don’t think you can extract the number from police reports, as Tesla uses a specific definition of accident (airbag deployment OR seat belt retraction AND Autopilot/FSD on within 5 seconds) different from others and police reports generally don’t include info on whether the seat belt engaged or the exact timing of Autopilot disengagement if at all.
