I'm optimistic for this area of tech and research in general, but agree we need to stop benchmarking against average human crash rates.
Although anyone can be hit at any time, the distribution of human crashes is not purely random. People who drive compromised, for example, are way overrepresented in those events.
So, theoretically, the tech could get to a point with a lower than expected crash rate for humans generally, but still increase your personal crash likelihood.
