Asher Moses completed The Knowledge, a memory test, and became a London black-cab driver in 1989. He said the test was very challenging and that he loved the excitement of graveyard shifts. London is the most incredible capital in the world, and I've been a cab driver in the city since 1989. Learning London's road map committed me to become a taxi driver. Memorizing the 46,000 London streets in the 6-mile radius around Charing Cross was one of the most challenging things I've ever done.
