Well, I had an incident where I was in the car waiting for my dad to come back and the handbrake gave way snapped and so... I was in a car rolling down a hill until the inevitable collision with a car, or a wall.
And no, I didn't touch the handbrake as the car got serviced and was found to be weak.
Not sure if that can be classed as a car accident, but it was an accident... in a car.
I'm in hysterics looking back on it now, and my friends never let me forget it.
