{ Installment 4 of Ivan Illich’s Energy and Equity series }

Net transfer of life-time

Unchecked speed is expensive, and progressively fewer can afford it. Each increment in the velocity of a vehicle results in an increase in the cost of propulsion and track construction and-most dramatically-in the space the vehicle devours while it is on the move. Past a certain threshold of energy consumption for the fastest passenger, a world-wide class structure of speed capitalists is created. The exchange-value of time becomes dominant, and this is reflected in language: time is spent, saved, invested, wasted, and employed. As societies put price tags on time, equity and vehicular speed correlate inversely.

High speed capitalizes a few people’s time at an enormous rate but, paradoxically, it does this at a high cost in time for all. In Bombay, only a very few people own cars. They can reach a provincial capital in one morning and make the trip once a week. Two generations ago, this would have been a week-long trek once a year. They now spend more time on more trips. But these same few also disrupt, with their cars, the traffic flow of thousands of bicycles and pedicabs that move through downtown Bombay at a rate of effective locomotion that is still superior to that of downtown Paris, London, or New York. The compounded, transport-related time expenditure within a society grows much faster than the time economies made by a few people on their speedy excursions. Traffic grows indefinitely with the availability of high-speed transports. Beyond a critical threshold, the output of the industrial complex established to move people costs a society more time than it saves. The marginal utility of an increment in the speed of a small number of people has for its price the growing marginal disutility of this acceleration for the great majority.
