I am driving on my way to work when I see this M3 hauling ass right behind me then quickly switches to left lane (4 way street). He keeps going passing other vehicles the same way. I chose not to get into it so I let him go. About 300 feet ahead I see him again. It seems like he is getting into the freeway just like I am. There is a car in front of him and the light is red, he has no option but wait. As soon as the light turns green he switches to the left lane and again starts hauling ass going past a motorcycle and merging on to the freeway at like 110 MPH. There was no pointing in playing cat and mouse so I didn't even bother. A few miles ahead I see the M3 again on the left lane going at about 70 MPH so I pull next to him and slow down. I thought he was waiting for me. As soon as I puled next to him instead of slowing down the M3 guy decides to goes up to 80 MPH. I usually not even bothered racing from such high speeds but I still honk 3 times and punched the throttle. The guy again backed out so I move to the right lane and go on my way. Immediately I see the M3 dropping gears and pulling away. Chasing him would be stupid, it's not like I am driving a GT500 to catch up. I don't see what this guy was up to but honestly its not impressing anyone.
