During the regular season, drivers earn points for their performance in races and can make the NASCAR Playoffs with enough points or a win. When the stock car behind gets within inches of the bumper of the race car in front, they both gain speed because the drag of the air is reduced for both of them. That pressure differential, low on top and high on the bottom, creates lift that allows the plane to soar through the air. As a result, drafting cannot be achieved throughout the entire race due to the engines overheating. [11] Some sources say that the most common tailgating does not save gasoline even at freeway speeds because one is likely to accelerate and brake so frequently that any aerodynamic savings are lost through the brakes.
