The discussion of how energy is used to move people requires a formal distinction between transport and transit as the two components of traffic. By traffic I mean any movement of people from one place to another when they are outside their homes. By transit I mean those movements that put human metabolic energy to use, and by transport, that mode of movement which relies on other sources of energy. These energy sources will henceforth be mostly motors, since animals compete fiercely with men for their food in an overpopulated world, unless they are thistle eaters like donkeys and camels.
As soon as people become tributaries of transport, not just when they travel for several days, but also on their daily trips, the contradictions between social justice and motorized power, between effective movement and higher speed, between personal freedom and engineered routing, become poignantly clear. Enforced dependence on auto-mobile machines then denies a community of self-propelled people just those values supposedly procured by improved transportation.
People move well on their feet. This primitive means of getting around will, on closer analysis, appear quite effective when compared with the lot of people in modern cities or on industrialized farms. It will appear particularly attractive once it has been understood that modern Americans walk, on the average, as many miles as their ancestors-most of them through tunnels, corridors, parking lots, and stores.
People on their feet are more or less equal. People solely dependent on their feet move on the spur of the moment, at three to four miles per hour, in any direction and to any place from which they are not legally or physically barred. An improvement on this native degree of mobility by new transport technology should be expected to safeguard these values and to add some new ones, such as greater range, time economies, comfort, or more opportunities for the disabled. So far this is not what has happened. Instead, the growth of the transportation industry has everywhere had the reverse effect. From the moment its machines could put more than a certain horsepower behind any one passenger, this industry has reduced equality among men, restricted their mobility to a system of industrially defined routes, and created time scarcity of unprecedented severity. As the speed of their vehicles crosses a threshold, citizens become transportation consumers on the daily loop that brings them back to their home, a circuit which the United States Department of Commerce calls a ``trip'' as opposed to the ``travel'' for which Americans leave home equipped with a toothbrush.
More energy fed into the transportation system means that more people move faster over a greater range in the course of every day. Everybody's daily radius expands at the expense of being able to drop in on an acquaintance or walk through the park on the way to work. Extremes of privilege are created at the cost of universal enslavement. An elite packs unlimited distance into a lifetime of pampered travel, while the majority spend a bigger slice of their existence on unwanted trips. The few mount their magic carpets to travel between distant points that their ephemeral presence renders both scarce and seductive, while the many are compelled to trip farther and faster and to spend more time preparing for and recovering from their trips.
In the United States, four-fifths of all man-hours on the road are those of commuters and shoppers who hardly ever get into a plane, while four-fifths of the mileage flown to conventions and resorts is covered year after year by the same 1.5 per cent of the population, usually those who are either well-to-do or professionally trained to do good. The speedier the vehicle, the larger the subsidy it gets from regressive taxation. Barely 0.2 per cent of the entire United States population can engage in self-chosen air travel more than once a year, and few other countries can support a jet set which is that large.
The captive tripper and the reckless traveler become equally dependent on transport. Neither can do without it. Occasional spurts to Acapulco or to a party congress dupe the ordinary passenger into believing that he has made it into the shrunk world of the powerfully rushed. The occasional chance to spend a few hours strapped into a high-powered seat makes him an accomplice in the distortion of human space, and prompts him to consent to the design of his country's geography around vehicles rather than around people. Man has evolved physically and culturally together with his cosmic niche. What for animals is their environment he has learned to make into his home. His self-consciousness requires as its complement a life-space and a life-time integrated by the pace at which he moves. If that relationship is determined by the velocity of vehicles rather than by the movement of people, man the architect is reduced to the status of a mere commuter.
The model American male devotes more than 1,600 hours a year to his car. He sits in it while it goes and while it stands idling. He parks it and searches for it. He earns the money to put down on it and to meet the monthly installments. He works to pay for gasoline, tolls, insurance, taxes, and tickets. He spends four of his sixteen waking hours on the road or gathering his resources for it. And this figure does not take into account the time consumed by other activities dictated by transport: time spent in hospitals, traffic courts, and garages; time spent watching automobile commercials or attending consumer education meetings to improve the quality of the next buy. The model American puts in 1,600 hours to get 7,500 miles: less than five miles per hour. In countries deprived of a transportation industry, people manage to do the same, walking wherever they want to go, and they allocate only 3 to 8 per cent of their society's time budget to traffic instead of 28 per cent. What distinguishes the traffic in rich countries from the traffic in poor countries is not more mileage per hour of life-time for the majority, but more hours of compulsory consumption of high doses of energy, packaged and unequally distributed by the transportation industry.
