AutoNation (AN) Americans love cars. Some of us even own multiple cars. In fact, the American car to adult ratio is over 1, with around 290M cars and 258M adults! That’s a lot of automobiles, and it may seem excessive. It probably is. America is a nation obsessed with excess, so this jives. That being said, owning a car is absolutely crucial in most parts of the country, especially if you live in rural America.
