the brain only pays attention to what it THINKS IT NEEDS to pay attention to. the brain is remarkably good at filtering out a ton of nonsense. so good that it filters out its own nonsense from time to time. so even though there are times when your brain might think “hey i should pay attention to whether or not my car is locked” there are plenty of other times when the brain just doesnt give a fuck about it. so even though muscle memory makes it happen, the brain has no care
