And over the course of a year their fleet has collectively driven somewhere around a million miles. Human drivers on US roads complete over 3 trillion miles per year.

So, one Cruise vehicle driving into concrete is about equivalent to 3 million human drivers driving into concrete on an equal rate basis.

Discrete events and very small numbers make it hard to draw good conclusions, and you shouldn’t extrapolate like that. With the exact same logic, you could have argued yesterday that Cruise vehicles are less likely to drive into concrete than humans with an extrapolated rate of zero! This claim is just as suspect as the other — n=1 just isn’t giving you enough data.

I was simply entertaining the 'statistic' posed by the parent at face value. But you're right, we don't know whether or not this is an outlier event.

You can set an upper limit with zero events.
