More than one person can be the same character.
First, make P1 choose the character you both want to be. Then unselect the character and move off of it. Move P2 over, and select the character. Go back one screen, then go into the character select again. You should both be on the same character. Both of you select the character. Do whatever you want from there on.
Note: In the character select screen and options, whenever one of you does an animation, both of you will. Also, if P2 chooses a different kind of vehicle than P1, P1 will look strange. Don't worry, this won't actually happen in the game.
I haven't tested this with P3 or P4 yet, but in theory, it should work.

POW Block Immunity
When you see the POW block on your screen and its about to hit you, just do the function you would normally use for a trick to create a shockwave for youself to become immune to the spin out the POW block creates (Control panel on GCN controller, Shaking Wii wheel, etc.). This can be done on both bikes and carts. Even though you don't loose speed or spin out, you still will loose the items you were carrying.

When the countdown starts wait till the 2 starts to disappear and then press and hold the 2 button. So the 2 must still be visible but disappearing.
This will give you a boost at the start of the race.
