London Black Cabs
The London Black Cab, or Hackney Carriage (as they may not always be black) is one of the most iconic symbols of London. This Christmas I was asked by Angeliki's brother-in-law what company made them (what brand). Oddly enough no one company makes all of them, unlike in cities like Berlin where almost every (yellow) taxi is a Mercedes, the Hackney Carriage is infact a style of vehicle which has been around since the 40s. From Austin, LTI or Metrocab. The most notable thing about the Hackney Carriage is that it has a 25ft turning circle which allows it to turn around in London's tight streets in one go, I doubt a New York Taxi could achieve such a feat!
London's Hackney Carrage drivers are the only ones allowed to stop and ply for trade on the streets of London without a booking, so if visiting London only ever hail a black cab otherwise you might not be so safe. The other advantage of a licensed London Cab driver is that he must has passed "The Knowledge", which is a test which is designed to ensure that the applicant knows every part of London inside and out. They are tested to ensure they can (without the assistance of a map) remember a selection of routes around London and the location of almost any street.
