Different Views
During standard gameplay, hold the "R" button on the third controller and press "B" to switch the view from the third-person behind the car angle to a first-person view from inside the car. Change this view to a side "drive-by" view by pressing "Y," "L" and "R" at the same time. Reset the camera angle to the original third-person view by holding "R" and pressing "A."
A Greater Challenge
Change some difficulty features by pressing buttons on the first controller while on the "Character Selection" screen. Hold the "L" and "R" buttons and press "Start" to play in the game's expert mode. This removes all destination and arrow indicators that help you find the best paths. To keep the destination indicator and remove only the arrow indicators, hold only "R" when you press "Start" from this screen.
Speedometer
Add a speedometer to your car so you can see how far above the speed limit you are really driving. On the third controller, hold "R" and press "X" five times during gameplay to activate this cheat.
Ride the Pedal Bike
You normally unlock the pedal bike after completing the 16 Crazy Box levels, but you can also use a cheat code to ride this bike at any time. While on the "Character Selection" screen, hold down "L" and "R." Release "L" and then release "R." Press these two buttons again and release them both simultaneously. Press "Start," and you will unlock the bike.
