You have zero expectation of privacy in public. If you don't want your tag read, time and date documented, with your picture, do what everyone else does and stick a fake paper plate on. If you're in a pickup, maybe try driving around with the tailgate down? Depending on the angle of the camera, that might afford some protection.

Some of the smaller burgs around Houston have installed them on roads leading in and out of their communities. Frankly, I think it's a waste of time unless they're looking for cheating spouses, that kind of thing. Any decent criminal has a fake paper tag on their ride when they're going to rob a house, knock over a liquor store, or do a drive by shooting.
