If anything goes wrong, there won't be time to hit the manual override. Mainly because we as passengers won't be paying much attention to whatever is going on outside. At the same time, panicky breaking maneuvers made by humans randomly overriding their steering system would probably be a bad idea anyway. Besides, humans are really lousy drivers. They should not be trusted to operate such vehicles at all. Machines will makes mistakes too, but I bet we'll see a lot less of them compared to the era of human pilots.
