In the early history of the auto revolution, racing was an incubator for all kinds of technology. From propulsion to engine tech to safety tech, the torture test of high-speed racing provided the basis for the auto industry to move ahead in leaps. Take one more recent example, tire tech. In the latter 20th-century radial tire tech still needed a proof of concept. Racing did it, and now all tires -- with a very few exceptions -- are safer for radial technology.
