More fun in created tracks
For more fun in creating tracks for stunts, just make
a little track in the form of an oval. This will make the track
legal. For the rest of the map, just do whatever desired.
Defeating Skid Vicious
Give Skid Vicious a jeep and choose a track with a jump. Skid will crash and burn.
Drive backwards for a short distance when the race
starts, then turn around and cross the finish line.
After crashing, set the replay until just before the point of impact. Choose the "Continue Driving" option to resume the race.
"Push" your opponent to the starting post and he will crash. You should stay where you are because your motion was slow. Make a "U"-turn and go a short distance back through the terrain. It will not work if you go through the road. Make another "U"-turn and go back on the road. It will show a penalty time, but as you drive through the finish line you will win because there are opponents in the race.
