Bump drafting is a technique used in racing, primarily in stock car and oval racing, where one car gently taps the rear bumper of the car in front to push it forward. This move allows both cars to reduce air resistance, increasing their combined speed. It’s most effective on high-speed tracks with long straights, such as Daytona or Talladega, where aerodynamics play a key role. The advantages of bump drafting include higher speeds and the ability to work together with teammates or other drivers
