Signal Light Phone

How do you get people to wait at a red signal light? Waiting at a signal light is boring. But it's so easy to make it fun!
Just let people communicate at red signal lights via a "signal light phone". The phones are connected with other signal light phones in different cities. So people who never met before can have a conversation while waiting for the light to change.
