No matter how you look at it you were speeding. The Sport car thing has nothing to do with. Flashing your lights has more to do with it. It seems like you were trying to conceal that you had a headlight out, and MANY people flash their lights thinking it will jar the radar (that gets under my skin). I got pulled over 5 times because I was black and driving a Bimmer, that is reason to complain. You just got caught speeding.
