<P> 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 . </P> <P> 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 more easily, 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 . The vehicle used must also be fitted with a lockable differential (common on 4x4s). The stunt was perfected and first performed at the 1964 World Fair by Tonny Peterson of Copenhagen, Denmark . </P> <P> The stunt has been used in many movies and television series, including Knight Rider, The Dukes of Hazzard, and two of the James Bond movies . The British stunt driver Russ Swift performs this maneuver as part of his shows and has achieved it in a wide range of vehicles including trucks . His son Paul also uses it in his displays and once rolled a Ford Fiesta whilst attempting to drive around Cardiff's Millennium Stadium at the Wales Rally GB in 2005 . </P>
