Sounds like he had it comming, I drive a T/A but would never pull up to anyone and laugh, even if it were a four cylinder, I had a guy in a IROC-Z do pretty much the same thing to me a few weeks back, I never start a race but this guy just kept agging me on, finally I gave in to temptation and blew his doors off, I finaly got out of it at around 120MPH, I could barely see the car he was so far behind me.
