Several major cities in the world are adding hybrid taxis to their taxicab fleets, led by San Francisco where hybrid represent almost 50% of its taxicab fleet by March 2010,4 and New York City where hybrids taxis represent 45% of the city's total fleet by September 2012. Unlike conventional gasoline cars, hybrids get better fuel economy, do well at slow speeds or idling, and have cleaner emissions.
