Just to clarify, I said *if they have a warrant*, I have no problem. That's what's in the Constitution - they have to have a warrant and probable cause. They can't just go on a fishing trip. That's the way it's been since the 1780s - at least in theory. I most certainly DO have a problem with a government agency attaching something to my car without a warrant OR my express permission (in this case a GPS).

Just for the record, I *do* have an EZ-Pass in my car. HOWEVER - if the cops want to use any information from that in a case, they have to get a warrant and present it to NH's Department of Transportation.
