Ya, I hear that. But the whole time the car is moving it’s phoning back location data. These thieves would have to be SUPER sophisticated in their attacks and even then, one slip in a very unique theft procedure and the whole operation is compromised entirely by some heavy weight consequences.
They can just turn off the internet connection. If that doesn't work then they can just destroy the transmitter/receiver if they are going to part it out anyways.
I just don’t really see it.
