About the term "drag racing"
Although the tiretracks of its history are clear, the origin of the term "drag racing" is not. The theories are almost as many and varied as the machines that have populated its ranks for five decades. Explanations range from a simple challenge ("Drag your car out of the garage and race me!') to geographical locale (the "main drag" was a city's main street, often the only one wide enough to accommodate two vehicles), to the mechanical (to "drag" the gears meant to hold the transmission in gear longer than normal).
