This reminds me of the time I ALMOST went down a hill while sitting half in, half out of the car. The car, a Plymouth Reliant, (a little car that sat low to the ground) had just been unloaded from a flatbed tow truck and the driver looked at me and said, "I need the keys." Well I couldn't get the key out (because he left it neutral, and I didn't know that the key can ONLY be removed when the car is in PARK) and so I flailed around and took the emergency brake off and IT ROLLED and would have gone down the HILL. But the saving grace was that it got caught, very firmly caught on that cement bar thing. Lots of men gathered suddenly and upon the advice of the police officer, the tow truck driver re-hooked the car and they heaved it back onto solid ground.
