It’s difficult for most people to remember a generic license plate for more than a few minutes and, unless an event happens, most people don’t review dash cam footage routinely. A photo on an open forum is static, easy to duplicate, and might invite stalking or other questionable anti-social behavior - the reason some cover their license plates on-line.I don't understand people who cover up their plates in a picture. It's not like everyone closes their eyes so they don't see your plate when you drive down the street. Drivers with dash cams record hundreds of plates during their drive. And then post their drive on youtube.
