i was in a black cab couple of weeks ago (please do not shout at me this is not my usual way of getting around town). Asked the driver how's business, expecting him to say things were a bit shit and instead he said never been better, how he thinks his is the best job in the world, he was playing golf that morning had a leisurely lunch etc.
He said that uber was a bit of a wobble when it was new but not an issue anymore far as he can tell, he said people have started using black cabs again at the same levels they were before the novelty of uber appeared . That's just one bloke's take on it though obvs.
