Carson City—located in the real town of Vårgårda, an hour from Volvo headquarters in Gothenburg—is the world’s only purpose-built simulated city for testing active safety systems. It’s run by Autoliv, a Swedish supplier that researches and manufactures safety components for nearly every car brand in the world. (Autoliv’s major clients are BMW, Mercedes, and Audi; Volvo develops most of its own systems.) Instead of choosing a Swedish name for the “town,” the company was inspired by Nevada’s state capital, particularly that city’s near-abandonment after the gold rush. (Plus, Carson City sounds a bit like the name of Autoliv’s CEO, Jan Carlson.) Indeed, entering the 0.7-mile-long strip is like stepping onto the set of an old Western film; it’s a one-block ghost town.
