“Im not using this because, um. PRIVACY! I pay cash for everything so the man can’t track me”.
But you carry a smart phone. Or have some sort of digital assistant in your home, or drive a vehicle with GPS and telematics in it, or walk around in public with your face exposed.
Any ILLUSION of privacy you have is more dangerous than understanding that said privacy went out the window a long time ago and adjusting to live in that world.
Go on with your false sense of security while every EZ pass (or similar system) photographs you and your license plate whenever you pass through it whether you have a transponder or not.
See those small tan boxes on poles with solar panels on them? Those are license plate readers. They’re active 24/7 and the gubment can use them to track your comings and goings. No warrant as you have no expectation of privacy in public places.
Combine that with your cell phone RSSI I formation and you’re pretty much trackable wherever you go. Once they can narrow the search to a smaller area, it’s only a matter of using facial recognition to figure it out.
Ever watch that FBI show on CBS? What the federal government has is at least 2 generations better than that. I’ve seen it in action and it’s pretty scary.
Privacy? You have none oh sweet summer child. It died around the time computers and surveillance cameras combined with wireless Internet via cell connection caught up to the Patriot Act.
