Ok, why do you get disqualified for pressing accelerate early, when you don't get a warning that will happen?
Ok, other than that, the only other issue is that turning during the race, would be a mistake. You can slightly tap the side arrow keys, and then go spinning in all sorts of directions not even thought possible.
Other than that, it's a fun game, one that needs a healthy dose of "Mr. P's Priceless Polish™", sold in all good medicinal stores.
