Detroit, Michigan — the Motor City — built the American automobile industry. Ford, General Motors, and Chrysler (now Stellantis) all have their roots in the Detroit metro area, and the city's identity is inseparable from the cars it produced. At its peak, Detroit was one of the wealthiest cities in America. Today, Michigan still employs more auto workers than any other state, though the industry has diversified geographically.

The modern auto landscape looks very different. Tesla moved its headquarters from California to Austin, Texas, where its Gigafactory produces electric vehicles at scale. BMW's largest factory in the world isn't in Germany — it's in Spartanburg, South Carolina. The American South has become a major auto manufacturing hub, with plants from Toyota, Honda, Nissan, Hyundai, and others dotting the region from Alabama to Tennessee to Georgia.

America's car culture extends beyond manufacturing. The Indianapolis Motor Speedway in Indiana has hosted the Indy 500 since 1911 — the oldest major auto race in the world. The Daytona International Speedway in Florida hosts NASCAR's crown jewel. The Bonneville Salt Flats in Utah are where land speed records have been set since 1914. California became the first state to mandate that all new cars sold by 2035 must be zero-emission, a policy that's reshaping the entire industry.

This quiz covers the full spectrum of America's relationship with the automobile — from manufacturing to racing to regulation. The states that built, drive, and race cars have shaped American culture in ways that no other form of transportation can match.
