Drafting
Transport/driving term: following closely to reduce air resistance
What the uneducated and under skilled drivers call Tailgating. Its when you follow closely behind another car traveling at a high rate of speed to decrease the amount of air resistance on your awesome sports car so as to save a little money on fuel or get up more speed to slingshot around him.
