"Cheap oil, which helped push the American Dream away from the city center, isn't so cheap anymore. As more and more families reconsider their dreams, land-use experts are beginning to ask whether $4-a-gallon gas is enough to change the way Americans have thought for half a century about where they live."

"Since the end of World War II, government policy has funded and encouraged the suburban lifestyle, subsidizing highways while starving mass transit and keeping gas taxes much lower than in some other countries."

"Federal spending is about 4 to 1 in favor of highways over transit. Today, more than 99 percent of the trips taken by U.S. residents are in cars or some other non-transit vehicle, largely as a result of decades of such unbalanced spending."

"The policies -- building so many highways and building so many houses near those highways -- have had a direct bearing on how and where people live and work. More Americans, 52 percent, live in the suburbs than anywhere else. The suburban growth rate exceeded 90 percent in the past decade."

"But there's been a radical shift in recent months. Americans drove 9.6 billion fewer highway miles in May than a year earlier. In the Washington area and elsewhere, mass transit ridership is setting records. Last year, transit trips nationwide topped 10.3 billion, a 50-year high."
