ELI5: What is autopilot in a human? Like why is it that I space out when driving for example and you have no idea how you got to where you are at or when your walking around and then suddenly its like you regained Consciousness after being absent minded?

Its often because of something you do repeatedly, your brain does it automatically. 

Like if you drive the same round to work everyday, all those days tend to becomes the same, and your brain doesnt really record the experience because it knows it so well.

You most likely still drive perfectly safely,  observing everything around you etc. Its just that your brain doesnt make a record of the memory. Then you cant recall that specific trip but you know the route like the back of your hand.
