I remember seeing the other car rapidly approaching, standing on the brakes, both feet, full weight, making impact, airbags popping open, my car stopping.....the air bags deflating, the other car sitting on the other side of the intersection with it's rear bumper laying on the ground. I thought the car was full of smoke, I opened the windows and realised it was the propellant from the air bags.
I don't think ever forget it.
