Transportation

After sixty years of almost constant increases in the annual number of miles Americans drive, since 2004 Americans have decreased their driving per-capita for eight years in a row. Driving miles per person are down especially sharply among Millennials, America’s largest generation that will increasingly dominate national transportation trends. But some skeptics have suggested that the apparent end of the Driving Boom might be just a temporary hiccup in the trend toward more driving for Americans. By the time Americans took notice of the decline in driving, the economy was in deep recession. Would economic growth bring back rapid increases in driving? Doubts about whether the Driving Boom has ended make it easier to postpone choices about transforming our transportation system or enacting reforms that disrupt well-established interest groups.

Americans drive fewer total miles today than we did eight years ago, and fewer per person than we did at the end of Bill Clinton’s first term. The unique combina­tion of conditions that fueled the Driving Boom—from cheap gas prices to the rapid expansion of the workforce during the Baby Boom generation—no longer exists. Meanwhile, a new generation—the Mil­lennials—is demanding a new American Dream less dependent on driving.
