The Motor City earned its nickname by putting the world on wheels in the early 1900s. Since then the automotive industry has continued to grow across the state in cities like Pontiac, Flint, and Lansing. Millions of cars and trucks roll off local assembly lines each year, as do parts from the many supplier companies that call the state home. In keeping with advancing trends in mobility, Michigan features two world-class autonomous vehicle testing sites, leading the nation in testing and development of next-generation transportation technology. As an added bonus, local manufacturers also produce bicycles, scooters, boats and even fire engines.
