LOL it is a bit tricky at 1st... but is controllable if you really utilize not mashing the gas all the time... you do that you're bound for trouble, and if you do use a good combination of the handbrake and brake... basically you're drifting... once you master that you'll tear through the corners... and even if you hit something/someone... you can get back on track alot quicker... not the easiest thing to do but practice makes perfect...
Only way this could have happened is if this guy had the game about a week before it came out... or maybe even by using cheats...
Love the game... since release I've been putting in at least 4-5 hours a night on this one!
