Planes are different in that there is a large ratio of passengers to "drivers". There isn't the same economic incentive to eliminate pilots when the cost of flying a plane is still going to be quite a few dollars a minute. The thing is, there are some conditions where people probably just shouldn't be driving. Like we shouldn't be driving in a heavy snow storm, at least not for most trips where you can just wait it out. Planes will wait out storms, even with human pilots. I don't see a problem with "level 4.9" cars that occasionally say "I'm going to wait out the storm" or that will avoid certain routes (such as "crazy mixing bowl" intersections where you can instead just take a side street)
