Tailgaters are just jealous because you own a Skyline and not a white . Or they spent twice as much money on a slower car that doesn't get the looks, and is half as fast. Or they just can't drive.
I try not to speed, generally, as points are an issue and Skylines attract enough attention as it is.
Just remember, if you are carrying a baseball bat / machete / fake gun, who is to say the other guy isn't carrying a real gun? Just be careful fellas.
