Skidpad
A skidpad is a large, circular area of flat pavement used for various tests of a car's handling. The most common skidpad use is testing lateral acceleration, measured in g.
The test is carried out on a circular track with a radius of 300 ft (100 m). A car driving on said track is slowly accelerated until the outermost tires on the car begin to slip. Going any faster would cause the car to drive outside the 300 ft radius. At this point, the speed of the car is recorded, and given the centripetal force formula mv²/r, a car's handling in terms of lateral g-forces can be derived.
