so, here's a quick lesson in the physics of optics: camera lenses are polarized - a feature utilized to eliminate glare. Well, here's a neat lil trick - if you take two polarized lenses and rotate them against each other - in other words, keep one fixed and rotate the other 0-90 degrees and look through the two lenses as you rotate them, you'll notice that less and less light is transmitted to the point that you reach 90 degrees and everything will be blocked out. Thus putting a polarized cover over your licence plate that has polarization running perpendicular to the camera lens will render a picture that is completely black. However, to the naked, non polarized eye, your plate is completely visible. So, a technique like this could keep you safe from traffic camera's. But radar guns aren't aimed at your license plate, they are aimed at your car and that is a different physics phenom involving velocity and light. to outsmart that you'd need the same paint that wonderwoman used on her lil jet...
