To be honest I think the true story here is:

> the fleet has traveled approximately 500,000 miles

Let's say they average 10mph, and say they operate 10 hours a day, that's 5,000 car-days of travel, or to put it another way about 30 cars over 6 months.

That's tiny! That's a robotaxi company that is literally smaller than a lot of taxi companies.

One crash in this context is going to just completely blow out their statistics. So it's kind of dumb to even talk about the statistics today. The real take away is that the Robotaxis don't really exist, they're in an experimental phase and we're not going to get real statistics until they're doing 1,000x that mileage, and that won't happen until they've built something that actually works and that may never happen.

By the law of large numbers, it's not a significant distance.

As long as there are still safety drivers, the data doesn't really tell you if the AI is any good. Unless you had reliable data about the number of interventions by the driver, which I assume Tesla doesn't provide.

Still damning that the data is so bad even then. Good data wouldn't tell us anything, the bad data likely means the AI is bad unless they were spectacularly unlucky. But since Tesla redacts all information, I'm not inclined to give them any benefit of the doubt here.

The comparison isn't really like-for-like. NHTSA SGO AV reports can include very minor, low-speed contact events that would often never show up as police-reported crashes for human drivers, meaning the Tesla crash count may be drawing from a broader category than the human baseline it's being compared to.

There's also a denominator problem. The mileage figure appears to be cumulative miles "as of November," while the crashes are drawn from a specific July-November window in Austin. It's not clear that those miles line up with the same geography and time period.

The sample size is tiny (nine crashes), uncertainty is huge, and the analysis doesn't distinguish between at-fault and not-at-fault incidents, or between preventable and non-preventable ones.

Also, the comparison to Waymo is stated without harmonizing crash definitions and reporting practices.

All these self driving and "drivers assistance" features like lane keeping exist to satisfy consumer demand for a way to multitask when driving. Tesla's is particularly cancerous, but all of them should be banned. I don't care how good you think your lane keeping in whatever car you have is, you won't need it if you keep your hands on the wheel, eyes on the road, and don't drive when drowsy. Turn it off and stop trying to delegate your responsibility for what your two ton speeding death machine does!
