“Safer” == “Safer than all other human drivers in the same city.” By their own admission, this is not a straightforward comparison. If they could do the math for the same routes, times of day, and conditions … maybe I’d believe it. Otherwise, this data is trivial to cherrypick, and they have every reason to present it as well as possible.
I believe Waymos are pretty safe, and that’s a great thing. “Safer than humans (for selected rides inside this area)” is still very good, but it’s not at all “Safer than humans (period).”
