Any Color You Like, As Long As It's Black

As Henry Ford said, "any color you like, as long as it's black." In 100 years, apparently some things have not really changed. I wonder why all the "black cars" in the city are black- seems arbitrary to just choose a color and it's not particularly distinctive from the other cars on the road the way yellow cabs are. Although the vehicle model is somewhat distinctive; I'm pretty sure nobody under 75 really drives these on a regular basis for their everyday car. This is from a sales site in Gowanus.
