haha.. Nice kill. Happens to me all the time too. At least you were going to be a good sport and possibly give him a thumbs up. I'm starting to get to the point where I wont even race anymore ricers. I've beaten too many of them and its just not fun anymore. Plus they annoy me.
I probibly would have done the same thing though if he was being that aggressive too. Look on the bright side, at least you didnt have to listen to any of his excuses.. "Wait till I hook up my turbo and i'll smoke your ***" or the "I wasnt going all out".
If the guys not being an *** to me, I'll throw them a thumbs up or if they got a nice car (even the 'stangs).
