What are those oval stickers with 2-3 capital letters in them? If the car is parked, I can get close enough to see that the letters are codes for different geographical locations, but you can't see that when you and the other car are on the road, so I don't quite get the concept. If I'm going to be envious, I need to be able to decode the things. Can anyone explain?
