I suspect most drivers have gotten out of their car and forgotten to put the shifter into park or apply the parking brake if the car is stick. I know I have, but when you have parked on a hill, you might put a little more thought into it.
If watching this young lady back up the driveway isn’t painful enough, what comes next is unreal. At the top of the driveway, she gets out of the car and walks back to pick up something on the driveway. Somehow she manages to avoid being crushed by the runaway Mercedes-Benz, only to get smoked by the driver’s door.
This one came VERY close to becoming a Darwin Award winner!
