From my understanding they can't make a photo ticket stick. when you get pulled over the first thing the officer does is look at your license and identify you. The camera identifies the bike/car and not you. So say it was not you, that you were letting someone else ride your bike, drive your car, and you are not sure of the time. In parts of Europe, to my understanding, they take a picture from the back and one from the front(to identify you.
