IMHO, this is not too bad! But obviously, coming from the software product industry, everyone knows that building features isn't the same as operating in practice and optimizing based on the use case, which takes a ton of time. Waymo has a huge head start, and it is evident that the "fully autonomous" robotaxi date is far behind what Elon is saying publicly. They will do it, but it is not as close as the hype suggest…

...why would "more than 10x less safe than a human driver" be "not too bad"?

The title makes it sound way worse than the 7 reported crashes listed in the article. I’d be interested to see a comparison with Waymo and other self driving technologies in the same area (assuming the exist).

Converting things to rates is how you understand them in a meaningful way, particularly for things that are planned to be expanded to full scale.

(The one thing I would like to see done differently here is including an error interval.)

Turns out Waymo hits a lot of things too. Why isn't Lidar stopping that?

Last I checked, Robotaxi has a safety driver, whereas Waymo is completely self driving, yet has a very good safety record. That speaks volumes to me. https://waymo.com/safety/impact/

When you have a CEO like Elon who swears up and down that you only need cameras for autonomous driving vehicles, and skimping out on crucial extras like Li-DAR, can anyone be surprised by this result? Tesla also likes to take the motto of "move fast and break things" to a fault.

The more I've looked into the topic the less I think the removal of lidar was a cost issue. I think there are a lot of benefits to simplifying your sensor tech stack, and while I won't pretend to know the best solution removing things like lidar and ultrasonic sensors seem to have been a decision about improving performance. By doubling down on cameras your technical team can remain focused on certain sensor technolo…

Having multiple sources of data is a benefit, not a problem. Entire signal processing and engineering domains exist to take advantage of this. Even the humble Kalyan filter lets you combine multiple noisy sources to get a more accurate result than would be possible if using any one source.

Completely self driving? Don't they go into a panic mode, stop the vehicle, then call back to a central location where a human driver can take remote control of the vehicle?

They've been seen doing this at crime scenes and in the middle of police traffic stops. That speaks volumes too.

This is the sort of thing that occurs when the interests of the public become subordinate to the interests of a lawless aristocracy. Financial, social and public safety considerations are costs that can be transferred to the public to preserve the wealth of a few individuals.

Was there a time when the interests of the public weren't subordinate?

To tell what? Waymo is easily 5 years ahead of the tech alone, let alone the roll out of autonomous service. They may eventually catch up but they are definitely behind.

What is Waymo's accident rate? (Edit: Tesla's is in the article, at least for that region.)

and there is a linked article about Waymo's data reporting, which is much more granular and detailed, whereas Tesla's is lumpy and redacted. Anyway, Waymo's data with more than 100M miles of self-supervised driving shows a 91% reduction in accidents vs humans. Tesla's is 10x the human accident rate according to the Austin data.
