Curious, what is "take control at a moments notice" in seconds? From what I've read about aviation, situations where really fast, let's say <2 seconds, reaction to an unusual situation is necessary don't seem very common compared to car traffic? (Excluding starts and landings, even if a plane can do those on autopilot the pilots certainly are going to be fully attentive)
It seems like an airliner flying at altitude has quite large safety margins compared to a car on a highway.
