We BMW drivers are not better than the rest, I just wanted to add to this pointless thread.
I meet regularly with a 328i coupe on the the road during my regular commute. He pulled up to me a few times, gave me once or twice the thumb up. Recently I was driving the GT3 RS just to add some miles, and he really wanted to race?? Same with a Kia optima with a big spoiler just a few miles later???
Some people just wants some fun I guess with no bad intent, not mean to chalange you. Maybe just see your car "in action". (It's hard to imagine someone really would want to chalange a GT3 RS with a Kia.)
