Social effects of motorized transport
Ivan Illich gives a set of very interesting
facts and figures when he discusses his concept of convivial transport:
- The United States puts between 25 and 45
per cent of its total energy (depending upon how one calculates this) into
vehicles: to make them, run them, and clear a right of way for them when
they roll, when they fly, and when they park. For the sole purpose of
transporting people, 250 million Americans allocate more fuel than is used
by 1.3 billion Chinese and Indians for all purposes.
- 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.
- Man, unaided by any tool, gets around
quite efficiently. He carries one gram of his weight over a kilometer in ten
minutes by expending 0.75 calories. Man on his feet is thermodynamically
more efficient than any motorized vehicle and most animals. For his weight,
he performs more work in locomotion than rats or oxen, less than horses or
sturgeon. At this rate of efficiency man settled the world and made its
history. At this rate peasant societies spend less than 5 per cent and
nomads less than 8 per cent of their respective social time budgets outside
the home or the encampment.
- 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.
- 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. In the bicycle system,
engineered roads are necessary only at certain points of dense traffic, and
people who live far from the surfaced path are not thereby automatically
isolated as they would be if they depended on cars or trains. The bicycle
has extended man's radius without shunting him onto roads he cannot walk.
Where he cannot ride his bike, he can usually push it.
- The bicycle also uses little space.
Eighteen bikes can be parked in the place of one car, thirty of them can
move along in the space devoured by a single automobile. It takes three
lanes of a given size to move 40,000 people across a bridge in one hour by
using automated trains, four to move them on buses, twelve to move them in
their cars, and only two lanes for them to pedal across on bicycles. Of all
these vehicles, only the bicycle really allows people to go from door to
door without walking. The cyclist can reach new destinations of his choice
without his tool creating new locations from which he is barred.
- Bicycles let people move with greater
speed without taking up significant amounts of scarce space, energy, or
time. They can spend fewer hours on each mile and still travel more miles in
a year. They can get the benefit of technological breakthroughs without
putting undue claims on the schedules, energy, or space of others. They
become masters of their own movements without blocking those of their
fellows. Their new tool creates only those demands which it can also
satisfy. Every increase in motorized speed creates new demands on space and
time. The use of the bicycle is self-limiting. It allows people to create a
new relationship between their life-space and their life-time, between their
territory and the pulse of their being, without destroying their inherited
balance. The advantages of modern self-powered traffic are obvious, and
ignored. That better traffic runs faster is asserted, but never proved.
Before they ask people to pay for it, those who propose acceleration should
try to display the evidence for their claim.
