>have largely given up on the problem That's a separate issue you're conflating. Human drivers have known weaknesses and known workarounds. Have a super dangerous stretch of road? Add loads and loads of bright orange signs for miles before with flashing lights. Still doesn't work? Close the road and redesign it according to what humans can reasonable handle. AIs are still so raw those weaknesses change on a regular basis and so opaque that no one is even trying to develop workarounds.
