　　Three Yale University professors agreed in a discussion that the automobile was what one of them called“Public Health Enemy No. 1 in this country.”Besides polluting the air and overcrowding the cities, cars are involved in more than half the disastrous accidents, and they contribute to heart disease“because we don't walk anywhere anymore”, said Dr. H. Richard Weinerman, professor of medicine and public health.

　　Speaking of many of these man-made dangers to the automobile, Arthur W. Galston, professor of biology, said it was possible to make a kerosene-burning turbine car that would“l(fā)essen smog by a very large factor.”But he expressed doubt whether Americans were willing to give up moving about the countryside at 90 miles an hour in a large vehicle.“America seems wedded to the motor car--every family has to have at least two, and one has to be a convertible (敞篷汽車) with 300 horsepower,”Professor Galston continued.“Is this the way of life that we choose because we treasure these values?”

　　For Professor Sears, part of the blame lies with“a society that regards profit (贏利) as a supreme value, under the illusion that anything that's technically possible is, therefore, morally justified”. Professor Sears also called the country's dependence on its modern automobiles“terrible economics”because of the large horsepower used simply“moving one individual to work.”But he admitted that Americans have painted themselves into a corner by allowing the national economy to become so dependent on the automobile industry.

　　“The solution”, Dr. Weinerman said,“is not to find a less dangerous fuel but a different system of inner-city transportation. Because of the increasing use of cars, public transportation has been allowed to wither (衰弱) and grow worse, so that if you can't walk to where you want to go, you have to have a car in most cities,”he declared. This, in turn, Dr. Weinerman contended, is responsible for the“arteriosclerosis”(動脈硬化) of public roads, for the pollution of the inner city and for the middle-class movement to the suburbs.
