Had an interesting comment from a client last week. He asked is that mytaxi on your phone. After clearing up the confusion created by my asking why his taxi would be on my phone he says it's a great app, always cars available and it's never sent me a driver with black skin (paraphrased) and goes on to say the drivers with black skin (paraphrased) won't use it because a few of them were audited, suggesting that he was well placed to know.
