Drivers will usually take advantage of this in the final laps by getting close to a lead competitor in precisely the wrong spot and unsticking their tires by manipulating their downforce stream. Swimmers -- both open water and pool rivals -- will often swim shut to another athlete to benefit from the slight vacuum and fewer-dense water created in the wake, and on the sides, of the lead swimmer. Following Chrysler in a hasty retreat from Airflows, DeSoto introduced extra-conventional -- and salable -- "Airstream" styling for 1935. It appeared on seven companion fashions bearing a Plymouth-like raked grille, slab sides, and rounded deck.

By tailgating, the identical results of reducing drag will pull a car along in the wake of the truck and add a number of miles per gallon as the smaller car's engine works less.
