I play games with people who sit in my blind spot, I've gotten people down to almost 45mph on 315 because they are to stupid to look at their own speedometer. You speed up, they speed up, you slow down, they slow down. You just can't win.
I respect bikers that respect the laws, I agree with the moving faster than traffic to stay one step ahead. The only bad experiences I have had with bikes are the left lane cruisers, not to turn this into another left lane rant thread or anything.
