You’re not wrong, but arguably that doesn’t invalidate the point, they do drive better than humans because they’re so much better at judging their own limitations.

If human drivers refused to enter dangerous intersections, stopped every time things started yup look dangerous, and handed off to a specialist to handle problems, driving might not produce the mountain of corpses it does today.

That said, you’re of course correct that they still have a long way to go in technical driving ability and handling of adverse conditions, but it’s interesting to consider that simple policy effectively enforced is enough to cancel out all the advantages that human drivers currently still have.
