On sonic riders dark desert how do the COM go fast on the spinning thing

it's because they're bots, and they can very easily just hold the arrow keys that makes them go really fast. for gamecube, xbox etc. users you have to spin it really really fast in order to complete the vortex fast enough at their pace. other then that, i dont think there's a cheat that helps you with it. and i know, it pisses me off :l
hope this helped :)
