Here's one that happened to me only a couple of weeks ago. I was just outside of London, UK on a particularly busy junction of the M25/A20. I was in a really slow queue, one of those when you realise that you should have actually exited, even if the exit wasn't yours, just to get out of the queue. Anyway a guy in a Mazda saloon was an front and obviously had the same idea because he tried to reverse past me on the inside through a gap that any idiot could see was narrower than his car. I knew he was going to side-swipe me and I could see his rear lights getting closer to my front wing, but wouldn't you believe it, my horn decided that this was the day it wasn't going to work, so I banged the steering wheel in vain as my lovely swedish steely crome bumper just squashed the side of his car as if it were marshmalllow. His side sustained a lot of damage, and mine just a slight crease in the wing by the side light and a line of his paint along my bumper. He couldn't believe it, but didn't hang around long after I let him go without any formalities.

My first car was sold to me by a guy who ran into, and demolished, a 300 year old dry flint wall in Wales. It had to have a new front end but apart from that was driveable.
