dbboy's experience of black cabs differs greatly from mine. Drivers who don't want to go south of the river. Drivers who agree to take you, but moan the whole way. Drivers who, despite doing "the knowledge", need directions to get to your house. Shouting at pedestrians for daring to cross the road. Plenty of bad eggs in that basket. Safety? Uber (or Addison Lee) is safer because there is a record of who picked you up and when. I don't want to drag out the obvious example, but a black cab driver could just as easily be a complete nutter as a minicab driver... and there's no record of you ever being in his car. I dare say black cabs will continue to have their place (taxi ranks outside stations for tourists, etc) but for most journeys, Uber is better in every conceivable way.
