Honk your Driver's Horn:
To make your driver honk their horn, press Select while racing. Each character's horn sounds different, too.
Player Select Tricks:
On the Player Select screen, press L to make the rotating image of the character you put the cursor on shoot a green shell straight ahead. You can also press R to make that character jump. Useless, but kind of cool.
