Sir this is a Wendy's, I mean a discussion about autonomous vehicles. The benchmark for the autonomous vehicles in the USA is in comparison to humans in the USA. That means autonomous vehicles need to go ~5,500 person-years worth of driving between crashes to equal the mean driver. The mean US driver is a very high bar to reach for technology, that is why Waymo has just maybe barely reached that bar after nearly two decades and billions of dollars.

That's between fatalities, not between crashes. The reported injury rate is 62 times higher than the fatality rate, and the overall police-reported crash rate is 170 times higher than the fatal crash rate.
