Bugs:
1. If you come to a halt directly under a time bonus then you will receive the time bonus every few seconds.
2. Select to race 'All Tracks' then, during the game, slam on the breaks with about 1 second left on the clock. The screen should go crazy and on the next course your distance travelled should be increased by a few 10s of kilometres.
3. If you hit a patch of oil, then, if you hit the pause key and wait until the sound stops, then you will have stopped sliding.
