Sonic is one of the fastest being in the world so you could not expect him driving trucks slowly. IN this game, you control the truck that Sonic drives and that is reason enough not to go slow.
Help Sonic reach the finish line before as fast as you can. If possible drive it faster than Sonic since that would make our hero very happy. Hell, he is known as the fastest animal around so you can’t expect him to be driving like that of a normal truck driver. There are rings that are scattered on the road, collect them for added points.
