In cycling, any time one bicyclist is riding behind another, energy is conserved, especially at higher speeds. This technique is common among hypermilers. This is called downforce which is most desirable especially on short tracks that have many turns. This pushes the oncoming air into the back wheel of the leading car and his front spoilers.
