How do i complete sonic at crisis city the fast sonic tornado part

Trust me I always hated that level, but if you had sonic adventure 2 battle it's just like the truck chasing you in city escape but a glicth (that happened to me) you see behind sonic while trying to dodge the truck. So all you have to do is dodge everthing that's behind you and keep a sharp eye for alot of surprises. If you keep practicing this you will defeat it, trust me I'm still stuck on the last story. (not to brag)
