new cars with tracking device?

Tweet

I was told tonight that all cars, trucks, etc from 2006 and up has a black box in it. I was told this is a tracking device so if you miss a payment, they can shut the car down from their office,,etc,,, I asked a dealership about this and it said it was a chip to help track it down if someone steals your car. Now who should I believe? It's bad enough the ez pass tracks your every where abouts and now your car? what is this world coming to?
