Thanks to the amount of science fiction on exactly this topic, it's like we can see our future - but we're choosing to ignore it. What they're trying to do, they're doing for "good" reasons - of that I'm sure. It's just that they don't understand the larger consequences, none of us do. And we (the general population) will continue to not understand until it is ultimately too late.
I have developed license plate-reading technology which can use a modern digital camera. Just put the technology in the hands of the masses and we can track our own cars.
