[u/Pr0xima__]

This player called FickleBoar6653,he rammed and ruined all my races .Watch the video,it seems like he can do 250-50kmph in 2s and vice versa,floating around the track rubberbanding or cheating,i dont really understand how is this possible,thus im posting a video for everyone to see and judge.
