Drivers will often take advantage of this in the last laps by getting close to a lead competitor in exactly the wrong spot and unsticking their tires by manipulating their downforce stream. Other drivers began imitating Johnson's technique, and drafting was born. The Los Angeles Memorial Coliseum in Los Angeles, California will host the 2023 Busch Light Clash at .

Johnson discovered during qualifying heats that if he pulled up close to the competition, within a few inches, he could keep pace with the bigger and faster vehicles. [20], Cooperative fluid dynamics techniques like drafting are also found in nature. The thought behind this is that when a car backs out, and then goes forward, it has used twice as much fuel for the same distance. Several races have been won by a savvy lead driver that allowed a trailing car to creep up from behind, stay there just a little too long, and leave the field with a heat-blown engine.

In tandem drafting, any sudden action by the leading driver is bound to lead to a crash. Along a long straight a car following close behind another uses the slipstream created by the lead car to close the gap between them, hoping to be able to overtake the leader under braking for the next corner, or if they have a straightline speed advantage, to pass on the straight.
