This is really an irrelevant question - but why does Uber make a big deal out of the colour of the car? They say on their website that a particular tier gets you a black car, and you say there something about black car drivers. Why would you care if your car is black, or red, or yellow, or whatever. I can understand not wanting a fucking pink car or something, but still.
Eg "Hop into the sleek black car", "Our classic black car option is the default". WTF?
Maybe it's a US thing - I'm from the UK and I have no idea why you would need a car of a particular colour.
