Just saw a Somerville Ford Fusion hybrid cab in Ball Square.

Maybe Green Cab is finally encouraging hybrid usage, as opposed to telling the press hybrids are "too small" and dangerous. One driver even told me personally that global warming was a liberal myth and that there was no need to be more efficient.

Hybrid Yellow Cabs of New York

By 2012, all cabs are supposed to by hybrids. On the streets yesterday I saw the following hybrid models: Toyota Prius, Camry, and Highlander; Ford Escape; Nissan Maxima; Honda Civic.
