Increased competition: The success of Ford and other carmakers sparked a wave of new competition in the auto industry. Dozens of new car companies were founded in the 1920s, including Chrysler, General Motors, and Packard. This competition led to a wide variety of new models and features being introduced, as well as a general improvement in quality.
Improved infrastructure: The growth of the auto industry put a strain on the nation's roads and highways. In response, the federal government began investing heavily in road construction, and by the end of the decade, there were over 200,000 miles of paved roads in the United States. This made it easier for people to travel by car, further increasing the demand for automobiles.
Cultural impact: The automobile had a profound impact on American culture in the 1920s. Cars gave people a new way to get around, and they quickly became a symbol of freedom and independence. The automobile also helped to shape the landscape of American cities, as suburbs grew up around car factories and dealerships.
