Many of the road-rage incedents that I've been involved with were mainly testosterone-pumped 16-twentysomethings that get REALLY pissed when their 'autozone' customized Camero got blown-out-of-the-water by a Taurus coughSHOcough. Mainly pulling off of stoplights.
I would have to admit that when I had some asshole tailgating me he would attempt to pass, I'd gun it, and all he'd have left was dust. He'd catch up about 3 miles later when I gave up. Then there is a lot of light-flashing and finger saluting. I usually just look and laugh.. <giggle>
