This is not as strong of an argument as you seem to think.

According to NHTSA [0] there are about 2.1 accidents per million miles driven. This includes fatality, injury-only and property-damage-only accidents. That is the equivalent of over 99.999% of miles driven without an accident. Over 5 nines of reliably consistent behavior.

This is a fair point but if what we're looking for is consistent behavior I think we'd have to consider events that don't result in damage or even rise to being accidents (but that could have, if fortune had frowned) like being cut off in a merge or someone running a no-turn-on-red. Which is of course difficult to really measure.
