These numbers have certainly skyrocketed in the past year. According to the U.S. Department of Transportation, as of 2014 there were 260.3 million total registered highway vehicles. For cars specifically, as of 2006 (the most recent year for which statistics were available) there were 135.3 million registered passenger cars.
That’s approximately one auto for every 2.2 or 2.3 Americans, a far more even ratio than the one auto for every 25 Americans back in 1916. And those numbers are likely to level even further as last year was the best year for auto sales in American history with 17.5 million, due largely to an improving economy and low gasoline prices.
