I think the world modeling is the part that autonomous cars can obviously be better at. They have all sorts of advantages over humans; access to much more detailed maps than the average person can recall, multiple types of sensors pointed in multiple directions, a system designed to integrate all that information in a way that is advantageous for driving (we have a system evolved for whatever it evolved for) and so on.

It's the sophisticated behaviors necessary to safely drive through that world model that are the issue.

The success of emergency breaking systems (that aren't advertised as "driving" assist) are pretty good evidence that the sensors can serve well as input to safe behaviors.
