So there I was driving, and some Mustang decides to tailgate me. I move over and he passes me, so I go and have some fun. Once there was an opening, I blew by him pretty good at 70% throttle. I thought Mustang GT's were faster than that? So I slow down, and his GF is waving frantically. I blow by him again and my wife waves back at her, only to be greeted by the finger. This was in my slow ass SLK 320. What's up with that? I was being nice and shit too!
