No one should be looking back.......its not up to them to let you by.
Hard to pass on that track especially if people aren't looking back at you. Even some of the people were looking back, seeing you riding their *** and accelerating harder, lose lose. On my dizzer some of the sportbikers were just retards, riding them the entire time for 2 laps and not letting me by. I eventually would just pull off to the pits and reset myself, seemed the safest way to go after passing a guy who wasn't letting me by on the inside, was kind of a dick move but hey, they said fair game in the morning, which is something I don't think you should say. lol
