I've just been driving behind a seicento with a tiny back window with TWO of these notices in What is the thinking..."Oh, well having these in my back window will stop people from ramming into me (more likely to if you ask me) OR I know, in order to show how much I love my children I'll limit the rear view vision in my car thus making it far more likely that I'll have a crash with my 'tiny people' in the car. OH PURLEASE....
