This has to be one of the coolest defenders of the Photoradar I have seen. It is a very thin peice of highly polished steel (or something ) about the thickness of a credit card. In the shape of a sharks tail.. ( just for looks i gather.. a square peice would be more goofy looking ) when you look at it streight on it cant be seen.. looks like a very thin black line down the center.. but from a side view... you cant make out the full plate. I was close up for the picture.. but if you step away, especially from the distance of the camera from the side, you cant see the left side of the plate at all....GENIOUS I SAY !!! I highlighted the second shot in red to make it more visable...
