In the US, Uber has an arch rival in Lyft. In the UK, however, Uber doesn't have such an obvious competitor. Sure, there's Mytaxi (formerly Hailo), Gett and Taxiapp for hailing black cabs, or Kabbee for booking minicabs, but no service that quite matches Uber blow for blow. That changes today with the London launch of Taxify -- an Uber clone that already operates in numerous cities around the world, including many in Europe. But how exactly does Taxify hope to compete with Uber, which has over 40,000 drivers roaming the capital? By giving drivers a bigger cut of the fare, and passengers a cheaper ride.
