There must be a psychiatric name for this.
Its common if you pay attention.
Yesterday I overshot the fuel pump a few feet so I had to back up.
Just then this other fellow pulls up behind as I was backing.
He immediately started shaking his head and acting very disturbed indeed. Even over exerting terribly on the gear shift.
Yet he parks gets out all smiles talking to the gas attendant like nothing happened... even tho seconds before he was in a rage.
So I'm thinking being in an automobile may enhance some part of the brain which releases something similar to the feeling of having a bigger ballsack.
