Funny, just had a similar experience this afternoon with another middle aged kid in his bright red sport model C-class Mercedes. I just tried to get away from him by slipping in and out of traffic at slightly over the limit, and he just kept following me like a yellow lab. Every light, he'd do his best to pull up close, and I just continued to ignore him. For what it's worth, it seems worse in this car than it was in my Z06 or Viper. I guess they think they have chance now...
