Instructions
Approach the corner you want to drift around at a sensible speed; hitting it at top speed will see you simply spin off the road and crash into other vehicles or pedestrians. Press the brake button to take the edge off your speed. (Press the handbrake button in conjunction with the brake button if you need to wipe off speed in a hurry.)
Push the left analog stick over to the right if you are heading into a righthand corner. Nudge the handbrake button for less than a second.
Push your left analog stick to the left as the back end of the car comes out and you begin to drift; you will now drift around the corner.
Press the accelerate button to end the drift as you come out of the corner; the back end of your car will snap back into place, and you will shoot down the road, ready to take on the next corner.
Press the brake button if you find yourself losing control of your drift and heading into oncoming traffic.
