New York City cabbies get a lot of flack—but it's hard out there for a hack! And as much as New Yorkers like to pretend they know where everything is in town (and will scoff at a driver for checking a GPS), the truth of the matter is most of them really don't—as 100 unlucky New Yorkers recently discovered. See, after stopping by a school for prospective cabbies, the Post decided to test the knowledge of some random townies and, well, the results were not so good! But how many of us really needs to know the boundaries of the World Trade Center site, anyway?

For its story, the tabloid asked ten simple questions, taken from the Master Cabbie Taxi Academy, of people on the street. Those ranged from "Which two major facilities are inside Flushing Meadows Park?" to "Where does Madison Avenue begin?, "Which museum is at 89th Street and Fifth Avenue?" to "Where is the Manhattan entrance to the Roosevelt Island Tram?" (Answers: CitiField and the USATA National Tennis Center, 23rd Street, the Guggenheim and 60th Street and Second Avenue). Not so hard, right? Not exactly. Not a single person they talked to was able to get all 10 questions right—and a depressing 12 percent got all of them wrong!

All of which is another reason to be a little nicer to your next cabbie. You still probably know your section of the outer boroughs better than them, and you absolutely have the right to pick whatever route you desire (for better or worse)—but they really do know their stuff. They may not be as insanely tested as London cabbies, but who is? Meanwhile, you can take the Post's full test here (we got 8/10).
