On a per-mile-driven basis, Tesla's self-driving accident rate is somewhere in the region of 5-10× that of human drivers, IIRC. And keep in mind that the self-driving here is already in a state of selection bias where it's more likely to be used in safer conditions (i.e., fully-grade-separated highway driving in clear conditions, rather than dense urban environments in inclement weather).

Maybe you were thinking the autopilot accident rate being 5-10x _less_ than human drivers?

> In the 2nd quarter, we recorded one crash for every 4.41 million miles driven in which drivers were using Autopilot technology (Autosteer and active safety features). For drivers who were not using Autopilot technology (no Autosteer and active safety features), we recorded one crash for every 1.2 million miles driven. By comparison, NHTSA’s most recent data shows that in the United States there is an automobile crash every 484,000 miles.

Tesla publishes these safety reports; the accident rate has held fairly steady quarter over quarter: https://www.tesla.com/VehicleSafetyReport

I know there are several wildly different statistics for Tesla's crash rate. Some of these statistics suffer from poor data quality, and the first big study saying "Tesla is safer than average drivers!" was really affected by this (I don't recall the exact details, but the consensus of pretty much everyone not Tesla was the statistics were complete garbage).

I mean if you have data feel free to present it like I did.

One immediately obvious issue is comparing Tesla vehicles, which are all relatively new vehicles typically owned by relatively older drivers to all other passenger vehicle.

The other immediately obvious issue is that the self driving features of a Tesla probably work best in ideal conditions, where human drivers also do.

You really can’t compare the average mile with the average autopilot mile. The best analogy I’ve heard is comparing human aircraft pilots (takeoffs, landings, weird old planes, all kinds of pilots) against aircraft autopilots only cruising at 30,000ft.

And how many disconnects do Teslas log per million miles on Autopilot? Because every disconnect is the car saying "I'm not good enough, humans are better than me".

More than that, if it's only doing the driving in ideal conditions, then it's unfair to compare the two. You need to compare against the human drivers in ideal conditions.
