That is a completely made up bar that is impossible to test for, and can never be met.
Even Waymo have tons of reported crashes in the same document.
Self driving cars need to be better than the average human - which means less injuries and deaths. Given 100 people will be killed on the road in the US today, it’s actually not a crazy high bar to clear.
> I see a lot of bar moving.
"Less than decent" means "worse than the average human driver".
I've never hit a stationary object, or any object for that matter, in 20 years of driving.
I understand that might not be the same for you. My bar is that it must be better than my own good driving.
