Drafting is a way to gain enough extra force to propel yourself around the car in front of you. This is why cars often run in drafting packs and lines, each gaining a few more miles per hour from the car in front and behind as pressure drag is reduced. Bicycle racers and speed skaters most often take advantage of drafting. That is why you do not see side mirrors on the vehicles, because it would cause a negative reduction in speed. During test sessions on the track, when Busch was pushed by his brother Kurt's Penske Racing teammate Brad Keselowski, they ran 15mph faster than single cars.
