When I was a child my mum used to leave me alone in the car with the engine still running, (it was safe to do this in the 70's!!) whilst she would pop in to the shops and I used to believe that the car may be able to drive off on its own. I would sit there absolutely, completely still in case I jogged it enough for it to drive off.
