a) well, no. we only have about 100 years dealing with these problems in context of driving cars and we're really bad at it; b) that seems like shifting goalposts, what we care about is whether driver's picture of the world is correct and actions are sensible with respect to that picture, it just so happens that driverless cars' picture is visual (or close to visual), but if you're judging them on entirety of input and side-effects it's only fair to judge our brains by the same standard.
