This last argument was important at a time when speed records were falling almost every year at the Indianapolis Speedway and many engineers were predicting stock car speeds of 70 or even 80 miles per hour.
The safety argument was even more persuasive. Throughout the 1920’s highway fatalities kept pace with the growth of the vehicle fleet and by 1924 had reached almost 20,000 per year.[1] Recognizing that the problem was national in scope, Secretary of Commerce Herbert Hoover convened the First National Conference on Street and Highway Safety in Washington in December 1924.
