motorized transport. A
walking man formerly could go where he pleased, go at his own pace
without observing any traffic regulations, and was independent of

obligations: license requirements, driver test, renewing registration,
insurance, maintenance required for safety, monthly payments on
purchase price. Moreover, the use of motorized transport is no longer
optional. Since the introduction of motorized transport the
arrangement of our cities has changed in such a way that the majority
of people no longer live within walking distance of their place of
employment, shopping areas and recreational opportunities, so that
they HAVE TO depend on the automobile for transportation. Or else they
must use public transportation, in which case they have even less
control over their own movement than when driving a car. Even the
walker's freedom is now greatly restricted. In the city he continually
has to stop and wait for traffic lights that are designed mainly to
serve auto traffic. In the country, motor traffic makes it dangerous
and unpleasant to walk along the highway. (Note the important point we
