They do not! Are you comparing computer driving in "easy" situations with human driving in all situations?
If we can get rid of, or vastly reduce, the problems of inattention, exhaustion, rage, chemical impairments and the like, we have a huge improvement. I think that improvement is vastly more, cost measured in human life, than the problems we see with computer control in odd situations.
So yes. They do drive better than humans. The fact that their failings are wack-doodle to us (you drove _right_ into that truck??) is swallowed in the fact that their failings are profoundly fewer than ours.
Better start showing off some statistics along with that claim.
This type of change isn’t instant, but it can happen faster than a human lifespan. Think about someone born in the 70s and what they’ve experienced with cigarettes. They were born into a world where close to half the US population smoked, and they’re now retiring in a world where smoking is de facto banned in most non-residential buildings. That is a drastic change, and remember that tobacco is addictive, which hampers change much more effectively than habits like driving.
That rules out de facto driving ban. That leaves driving ban by fiat. Also never gonna happen in this century, unless it carves out an exception for "classic cars."
As far as hazard ratios go, cigarette smoking is orders of magnitude more dangerous than driving. Not a good comparison.
I’m not, you didn’t read what I wrote. I specifically predicated my theory on if it was possible, and indicated my reservations there.

But the big benefit that I see of self-driving is that a lot of manual driving becomes safer. Autonomous vehicles won't overlook motorcycles and Miatas.
Autonomous cars will go a long way to making small, fun vehicles safe again.
