Bicycles Are Faster Than Cars

Langebro Stand
We're no strangers to the legendary 'Energy and Equity' essay by Ivan Illich from 1976. We have the first chapter here on Copenhagenize, but Andreas sent us a link to an excerpt from it at No Tech Magazine.

Which then led us to discover that the good people at Clever Cycles have slapped the whole essay on their site.

This excerpt is about how bicycles are faster than cars. As Andreas puts it, "Calculations are from the 70's, but I like the idea of the overall miles pr hour comparison between modes of transport, and am thinking that the figures might even be more advantageous for bikes these days."

"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."

"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."

"Man on a bicycle can go three or four times faster than the pedestrian, but uses five times less energy in the process. He carries one gram of his weight over a kilometer of flat road at an expense of only 0.15 calories. The bicycle is the perfect transducer to match man’s metabolic energy to the impedance of locomotion. Equipped with this tool, man outstrips the efficiency of not only all machines but all other animals as well. The bicycle lifted man’s auto-mobility into a new order, beyond which progress is theoretically not possible."

"Bicycles are not only thermodynamically efficient, they are also cheap. With his much lower salary, the Chinese acquires his durable bicycle in a fraction of the working hours an American devotes to the purchase of his obsolescent car. The cost of public utilities needed to facilitate bicycle traffic versus the price of an infrastructure tailored to high speeds is proportionately even less than the price differential of the vehicles used in the two systems."
