Best lessons-hardest learned and I believe it is my duty to educate other motorists so I let them run into it safe in the knowledge that they'll only do it once (without a trip to the bodyshop at least).
But seriously, I know what you mean, the number of people who drive right up my a*** as if that will make me go faster, even when I'm in traffic, or perhaps they think that with a 4L V8 my car is so underpowered that I'm the one causing the holdup!
