Also included at some demolition derbies in the US and UK are rollover competitions, where the object is to drive a car so that only the wheels on one side hit a ramp, causing the vehicle to roll over repeatedly.  Drivers take multiple runs at the ramp until their vehicle dies.  The driver who completes the most rollovers before their vehicle ceases to function is declared the winner.  Compact cars, especially [[hatchback]]s, are used in rollover competitions.  Their lighter weight enables them to roll more easily than larger vehicles. However, with modern high-horsepower unibody sedans and coupes now appearing on salvage lots, some of this conventional wisdom is being questioned and some major competitions have been won by drivers of small size, mid-size and full-size sedans.
