I'm an adult, white guy with lots of gray hair... but I live in Brazil. BTW, other day I was talking to a black guy friend of mine. He was complaining that the taxis didn't even stopped for him. More than one he had to ask as policeman to stop a taxi for him. As a funny guy, he says that he asks the policeman: "Would you please stop a taxi for me. I'm not able to do it, maybe they are thinking I'm black!".
