Hitting nitrous torques the chassis back, giving the rear tires immensely more 
weight under the new acceleration. The end effect is that you will go straight. 
If you find your tail sliding out or are about to spin out of control, hit your 
nitrous. You will be surprised at how fast you will get straight again. This is 
a great trick in combination with Speedbreaker. With the correct timing, there 
is no corner you cannot take at any speed.
