And yet there is no evidence that self-driving systems are any safer than human drivers, or that they'll ever even be as safe as human drivers, let alone safer than them.
What do you mean "no evidence"? The companies testing self-driving cars now have hundreds of millions of miles driven and I haven't seen any reliable report showing they have higher kill rates than human drivers.
It would seem entirely possible that large amounts of highway driving can be handled by self-driving cars with slightly lower rates of accidents (tired and drunk people kill a lot of people!)
