When ever I'm on my final lap on Mobius Strip and the robot activates gravity drive while I'm in first place, my I start to spin around uncontrollably and there's nothing i can do to get out of it until gravity drive stops. It really sucks cause it puts me in last place and then i can't come back from it. This is really makin' me crazy:#!!! Is there anybody who knows WTF is goin' on w/ this and how I stop it from happening so I beat this thing? Thanx

This is what happened to me. But it's because I hadn't any GP(gravity points).Perform tricks on ramps to earn them. Also, you see when green glasses coming out of the ground sometimes?
Hit them and you will speed up, as well as you will get GP.
If you're spinning while you have GP, then this is a glitch.
