Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure required to maintain a certain speed and can also slightly reduce the energy expenditure of the lead vehicle or object. The following driver can also pull a similar tactic, inching up on the car ahead in order to disrupt the flow of air over the lead car's body. The side drafting technique is only beneficial for one car as it negatively affects the other car.The rear car pulls up to the side of the front car while keeping the nose of the car close to the front cars back wheel.This pushes the oncoming air onto the front cars spoiler, causing it to lose speed and slow down.

He has ridden the draft to 10 combined points wins at restrictor-plate races, including last year's Coke Zero 400. It is important to understand the aerodynamic behaviour of a motor vehicle when drafting, for example if the rear car is too close to the front car, the air supply to its radiator will be reduced and there is a possibility of the engine overheating. In 1960, at the second Daytona 500, Johnson was behind the wheel of an under powered Chevrolet in competition with several dominant Pontiac cars on the track at that time including one driven by Bobby Johns.
