"If the cars autopilot hands over control, it's likely to be mere seconds before disaster strikes"
That's obviously not true. An automatic car would just perform an emergency stop - the main objective of the software will always be to ensure that it can come to a complete stop in the space available. If it can't do that, nor can the driver.
Cars will need to hand over control based on areas where the road layout is unsuitable - maybe around schools and other busy areas which would presumably be included on the maps so the car can usually drive around. Also changes in weather conditions may result in the software being unable to safely operate automatically.
