Down through the ages the three essential requirements for the continued existence of the human race have been food, clothing and shelter. These essentials are still fundamental, but with the development of social and economic phases of civilization, as distinct from the mere struggle for existence, the fourth element—transportation—has become equally important. It is impossible to conceive life as we know it without the facilities for moving men and materials from place to place. Today we are living in an age that is absolutely dependent on an abundant supply of fossilized fuel, and the automobile, although still in an early stage of development, represents the most useful and convenient form of transportation available to civilized peoples.
