That’s probably true, but their handling of edge cases will only get better the more time they spend on the roads, and it already looks like they’re significantly safer than humans under normal circumstances, which make up the vast majority of the time spent on the road.
As long as the overall number of injuries/deaths is lower for autonomous vehicles (and as you’ve acknowledged, that does seem to be what the data shows), I don’t care how “stupid” autonomous vehicles’ accidents are. Not to mention that their safety records will only improve as they get more time on the roads.
