Even though the automobile is king of the American commute
, some US cities can still do boast an impressively green travel rate. 68 percent of New Yorkers travel by either bike, walking or the city's transit system, according to research conducted by the League of American Bicyclists. Washington DC and Boston also had high shares of non-drivers - 53.1 and 50.7 percent respectively. Even though some cities are turning their back on the automobile, this is not the case across the rest of the country. 76 percent of Americans travel to work alone by car.
