Glitch: Get away with stop-go penalties:
If the screen appears stating that you have a stop-go penalty and pit in three laps, pause game play. Select "Replay" at the pause menu and watch the replay for a bit. When you continue the race, it would have disappeared and you do not have to do the stop-go penalty.
