That's a good idea. I think I should do something more explicit like a popup the first time you get a traffic-control message. They are in a different color but they are not that different (they're orange). I am going to make 'm flash anyway to make 'm stand out but having a popup or something when it's the first time is a good idea. Or I might do it that the first time you are caught for not following traffic control (or not responding to traffic control) that they let you off with a warning and an explanation of how it works.
