People worry a lot about ebola. But what about the dangers of forgetting to set your parking brake?

We’ve all seen cars roll away when parked, because the driver forgot to set the parking brake, especially when they are warming up their cars. Not to mention the classic problem of the clutch slipping when you parked on a hill in a higher gear, and eventually the car rolling off.

As you car rolls down the hill, it could hit you. You could be instantly crushed by your car and die.
