This actually happened!
I live in Edinbourgh, Scotland. I'm on a tour bus showing a friend around. Behind us is this huge Texan. We knew knew this because he told everyone very loudly when anyone got on the bus.
The bus stops at a red light and he hears a beeping sound. He asks what it is and I tell him it's the sound to let blind people know when the traffic has stopped. He says, "Oh! In our country we just don't let our blind drive!"
