I believed for years that cars had auto-pilot. I would always fall asleep on road trips, and was amazed that my father could stay awake. He told me he didn't - he turned on auto-pilot. I started to suspect once when he DID fall asleep driving, but then rationalized that he just forgot to turn it on.
