Tired of playing (and winning) Racing League and/or Free Tracks? Try:
1. Driving the course in reverse gear,
2. Driving the course in the opposite direction, driving slowly in order to take in the scenery (rather pleasant),
3. Driving the course in the opposite direction for one lap, and then turning to chase the other three cars. You might be surprised at what you find,
3. Driving the course in the oposite direction until you find a really narrow part, wait for the other three cars to arrive, and then blast, or charge at them [the bridge in Desert Island is a good site to choose for this activity].
