Real time traffic tracking

This isn’t your father’s real time traffic tracking. This is personal. Technology has been out for awhile now that can read a license plate in traffic from a distance. So what’s the news? Apparently G2 Tactics in Virginia invisions a day when its cheap enough for anyone to buy. We could all track each other’s driving patterns. Groups could buy or lease the equipment and re-sell data to information brokers, who in turn can sell that information to nearly anyone with a check. I find the technology itself fascinating, but the privacy implications(or lack there of) frightening.
