I never have an issue with tailgaters... maybe it has to do with how fast I drive.
I had this friend when I lived in Florida who drove a huge, jacked-up pickup... and he was the type of guy that you would want on your side in a fight because he is kinda nuts and doesn't hold back. Anyway, one day he was supposed to meet me for a few drinks after work. I get a call from him on my way there, and he says very calmly, "I'm going to be late... I'm about to be in an accident."
So he finally arrives and explains that this asshole was tailgating him really close, so he hit his brakes suddenly. Of course the asshole can't react quick enough, so his car is wedged up under my friend's truck... the front end totally destroyed... and barely a scratch on the truck. I thought it was pretty hilarious.
