Hi,
I think to make the races more exciting every so often on the track you crash through a set of bonus cards which give you a special "Cheat" on the track. it might be a banana peel to spin out your opponent, a turtle shell to wreck your opponent, a flashing star to make you invinciable and speed you up, or even a bullet to take your way to the front if you're way behind. no othe racing game has done this and this could be really innovative. That's why I think.
