To get the pace car, hold down the START button and the brake pedal
while choosing transmissions. Keep holding it until the race starts.
Police Car Cameo:
Press the START and VIEW buttons while holding the BRAKE and
ACCELERATE peddles. Next, select automatic or manual transmission,
then press START, VIEW, BRAKE and ACCELERATE again. If you did it
right, a police car will appear and run the course backwards.
Turbo Charged Engine:
First choose manual transmission. When you are racing and you are in
sixth gear go into the pit area. If you did this right it will switch
you into first gear and you will be going about 265 mph in first gear!
