In San Francisco, you can make a choice to use a cab that is better for the environment at the same price as any other taxi. Green cabs use hybrid Toyota Prius or CNG (natural gas vehicles) before dispatching any other cabs. It’s a great advantage for San Francisco taxis and being seen in many other cities such as Phoenix. The cabs are better for our environment, and help reduce operating costs (fuel) for their operators. Try a green cab and let us know what you think!
