In 1909 the Ford Model T won a difficult automobile race from New York City to Seattle. The victory ushered in a change in the country. Between 1910, when the Model T went into mass production, and 1930, the year after the stock market crash, automobile registration in the United States went from 458,000 to 22 million. The boom in automobiles transformed the American landscape. Cars made longer commutes possible and sparked the expansion of the suburbs. To accommodate the new vehicles, roads were paved, downtown streets were widened, and bridges and tunnels were built. In many ways, the Model T made the America we know today.
