There are lots of differences, but one is that situations requiring aircraft pilot intervention often have a timeline measured in minutes. The recommended procedure for handling an emergency situation is to pull the checklist for that situation before starting to ensure you don't miss anything. Even urgent situations, like a TCAS alert, will often give 30 seconds warning. By contrast, this driver had roughly 2 seconds to notice that the autopilot was silently failing to handle the situation and to apply the brakes to prevent a collision.
