If the court can't see your face, how can they confirm it was you driving and speeding. This isn't a problem with real cops because they obviously come up and talk to you. If there's no good mug shot, there's no proof. This is why those cameras face both forward and back, that way you get your mug taken and the license plate at the same time. Bang, proof. That won't work so well with a tinted visor. Haha
