Is that green vehicle really a cab?

If you've seen any lime-green taxi cabs at a few spots around the borough, you're not having any problems with your color vision.

Following months of opposition and litigation  from the yellow-cab industry, the Bloomberg administration finally got the go-ahead from the courts, and has now enabled cabs to pick up fares on the street in the so-called "outer boroughs" and in upper Manhattan, where yellow cabs rarely tread.

Brooklyn, Staten Island, Queens, and the Bronx have been served mainly by livery cabs which are supposed to only take fares which are called in, although many livery drivers regularly – and  illegally – pick up fares on the street at busy spots like subway stations and shopping malls.

Plans are to eventually have some 18,000 green cabs and transformed livery cabs on the streets in the four boroughs, phased in over the next three years.
