I don't try it with other cars/tracks yet. Its only happens with "Director mode" (You can see mode i'l choosen at the beginning and end of the video) You can see this bug at: 1:09-1:16 2:37-3:25 4:29-5:09
Were there any other cars on track? It works weirdly in replays when there are more cars on screen than set to visible in options.
