Workers in the San Francisco Bay Area made the nation’s most dramatic shift from commuting via automobile to using alternative transportation between 2006 and 2013, according to a new Census Bureau report.
 
 Commuting by private car in the densely populated region, including carpooling, dropped from 73.6 percent of workers in 2006 to 69.8 percent seven years later, giving it the nation’s third highest level of alternative commuting.
 
 Commuters in the New York City-centered metropolitan area were least likely to use private cars to get to their jobs in 2013, but even so, a majority – 56.9 percent – still did. Ithaca, NY, had the second lowest use of cars, 68.7 percent, followed by the San Francisco Bay.
