ROAD DATA— “Automobile accidents in the U.S. are now the subject of a large-scale investigation as if they were an epidemic—as they are. The Department of the Army, the American Medical Association and other major groups are studying many phases of the matter, from the design of tollbooths to the personality of truck drivers. Among other significant findings are that sedatives and tranquilizing drugs dull a driver’s skill, and that the dangerous effects of an evening of drinking may last as long as 18 hours, regardless of coffee therapy.”
