You're walking down the street, and you pass a cab. Nothing out of the ordinary, it seems, except instead of the traditional yellow the cab is painted a sickly neon green. You rub your eyes. Yup, still green. That's because you've just happened upon an Outer Borough Taxi, one of more than 1,000 already on the road since the program opened in June. For those of us who live in the outer boroughs (read: most of us), this is welcome news: There's nothing worse than standing on a street corner for 20 minutes waving your hands around like and idiot trying to catch a yellow cab that will never come. So why might Bill de Blasio shut down the program when he transitions into office?
