One of my friends was driving home from a restaurant one
night with his mate and their girlfriends. Quite legitimately
they overtook a car on a quiet country road. The guy in the
other car took offence to this and, pretended to swerve into
my friend. I'm pretty sure that he only did it to scare my
mate, nevertheless he thought that the guy was actually
going to hit his car. He reacted by turning sharply to the right
to avoid what he thought was going to be a collision and
smashed his car up the bank. His beautiful girlfriend was
thrown from the car and killed instantly.
