> Using human crash data, Waymo estimated that human drivers on the same roads would get into 78 crashes serious enough to trigger an airbag. By comparison, Waymo’s driverless vehicles only got into 13 airbag crashes. That represents an 83 percent reduction in airbag crashes relative to typical human drivers.

> This is slightly worse than last September, when Waymo estimated an 84 percent reduction in airbag crashes over Waymo’s first 21 million miles.

nitpick: Is it really slightly worse, or is it "effectively unchanged" with such sparse numbers? At a glance, the sentence is misleading even though it might be correct on paper. Could've said: "This improvement holds from last September..."

I wonder how many of those airbag crashes were an At-fault or shared-fault of the Waymo AVs.

Assuming you trust Waymo's account, the article details them, saying the following:

>So that’s a total of 34 crashes. I don’t want to make categorical statements about these crashes because in most cases I only have Waymo’s side of the story. But it doesn’t seem like Waymo was at fault in any of them.

Back when I used to pay attention to this stuff, the vast majority of crashes occurred when the Waymo vehicle was rear-ended while stopped at a traffic light.
