Ski (driving stunt)

Skiing is an automotive driving stunt where the car is driven while balanced only on two wheels, either the pair on the driver side or on the passenger side, but not the two front tires, or two opposite corners.The stunt is generally performed by driving one pair of wheels up on a ramp to lift one side of the car. Alternately, the stunt can be done in a vehicle with a high center of gravity (such as a 4x4 or SUV) by turning sharply or at speed. This technique is more dangerous because there is a strong possibility of the vehicle tipping completely over. Another technique is to let some air out of the tires that will be on the ground, so that the car can tip easier, as well as keep its balance better. Once up on two wheels, the car has to be balanced by steering (much as one would when riding a bicycle) which makes it necessary to drive more or less in a straight line.
