This is completely twisted and violates every right to freedom, privacy, liberty and the right to be secure in our persons. Your car is private property is it not? What gives the Gov the power to alter your car by adding a foreign device to it?
Amendment IV
"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
What they are attempting is a 'search' for information on private individuals by using GPS tracking. And they do this by trespassing on private property without notifying the owner let alone attempting to get their consent. It is clearly unconstitutional.
Can’t they do this with Onstar, etc. anyway? The cell phone (sat phone?) has already been used to listen in to conversations in the vehicle.
