Why? If computer-driven cars are much less likely to crash than human-driven cars, it would be entirely appropriate for there to be a social stigma against humans driving cars (because it would show disregard for the lives and safety of others). It would also be entirely appropriate to treat human drivers more harshly when they were responsible for accidents, as they would have had the choice of instead allowing a computer to drive and statistically probably avoid the accident.

You misinterpreted my sentence (but perhaps it wasn't your fault since I elided a crucial piece of information).

I did not say that human-driving ought not be morally blameworthy but, since I enjoy driving, I am understandably worried about a time when something that brings me pleasure will become unethical.

I suspect you will then be able to exercise driving in a more controlled, and most likely more interesting than everyday city driving, environment the same way it is now for kart circuits and the like.
