It took more than a couple of legal strategems, but New York City's mayor Michael Bloomberg has outwitted the city's powerful yellow taxi lobby. The State Legislature passed a bill making it legal for New Yorkers to hail livery cabs from the street. What's a livery cab? It's a private taxi, unmarked, often a Town Car, usually found in areas in and outside of Manhattan that aren't well served by yellow taxis. They don't run on meters, either; a fare is agreed upon between the rider and driver.
