Only that’s not what they’re selling us - they say autonomous cars are safer than humans, fewer accidents per mile driven, faster reaction times yadda yadda. I think this implies quality and not respecting speed limits is not something that sounds very high-quality. At least not while they have to share the road with humans.

Autonomous cars can run headlong into concrete walls and still be substantially better drivers than humans. There is no inherent contradiction there at all. They can speed and still be more law-abiding than humans too, humans get pretty casual about speed limits. I don't think you've grappled with just how bad humans are at operating rolling tin cans travelling at speeds evolution has not prepared us to move at. We're really bad at it. Autonomous cars aren't ever going to be perfect, they are merely a better alternative than humans.
