It is pretty incredible but people will (rightly so?) hold automated drivers to an ultra high standard. If automated driving systems cause accidents at anywhere near the human rate, it'll be outlawed pretty quickly.

This is evidently false. Robotaxi crash rates exceed human drivers', but there's not an effective regulatory agency to outlaw them!

According to that article, Waymo crashes 2.3x more often than human drivers (every 98k miles vs 229k miles), which is clearly false. I think it's far more likely that humans don't report most minor collisions to insurance, and that both Robotaxis and Waymo are safer than human drivers on average.

Why is it clearly false? It might be false, but clearly? I would definitely like to see evidence either way.

That sounds like you are trying to find reasons to get the conclusion you want.

The NHTSA requires a report when any automated driving system hits any object at any speed, or if anything else hits the ADS vehicle resulting damage that is reasonably expected to exceed $1,000.[1] In practice, this means that everyone reports any ADS collision, since trading paint between two vehicles can result in >$1k in damage total.

If you go to the NHTSA's page regarding their Standing General Order[2] and download the CSV of all ADS incidents[3], you can filter where the reporting entity is Waymo and find 520 rows. If you filter where the vehicle was stopped or parked, you'll find 318 crashes. If you scan through the narrative column, you'll see things like a Waymo yielding to pedestrians in a crosswalk and getting rear-ended, or waiting for a red light to change and getting rear-ended, or yielding to a pickup truck that then shifted into reverse and backed into the Waymo. In other words: the majority of Waymo collisions are due to human drivers.

So either Waymos are ridiculously unlucky, or when these sorts of things happen between two human driven cars, it's rarely reported to insurance. In my experience, if there's only minor damage, both parties exchange contact info and don't involve the authorities. Maybe one compensates the other for damage, or maybe neither party cares enough about a minor dent or scrape to deal with it. I've done this when someone rear-ended me, and I know my parents have done it when they've had collisions.

If human driven vehicles really did average 229k miles between any collision of any kind, we'd see many more pristine older vehicles. But if you pay attention to other cars on the road or in parking lots, you'll see far more dents and scratches than would be expected from that statistic. And that's not even counting the damage that gets repaired!

Definitely. I looked at Tesla's source for these numbers, looks like they primarily used data sourced from police reports, which most people only file if the incident is serious enough to turn into insurance.

Tesla notes:
