Use small brief motions to continue your drift. Adding too much spin to your drift will send your vehicle in a constant swerve. Remove your finger from the screen and your vehicle will slowly straighten out. This may help if you are out of control in the middle of a series of turns. If you can reset your vehicle's orientation, you may be able to regain drift control. The level layout is static. Memorize the track and try to do better with each subsequent run.
