It was a bit tongue-in-cheek - the median driver has precisely zero accidents in any given year. I don't really know how to think about it. Accident rate, on a per-mile basis, falls out of some combination of "hardness of the driving problem" (freeways have many fewer accidents than city streets, I think) as well as propensity to take risks (driving at night; in bad weather; at higher speeds; while distracted) as well as driving skill. What, by definition, people will accept is an accident rate similar to that for professional drivers; e.g. taxi/rideshare/livery. According to a report by Uber, that's about half the number of fatal accidents on a VMT basis versus the general population in their case.
