Seems like a pointless gesture.
If you want to commit a terrorist act you simply cover your car’s satellite antenna with a bit of foil or unplug the antenna. Disable the satellite tracker in some way and you are off the radar.
If the government asks you why your tracker was off? My car was in the garage all day, my car broke down and the battery went dead. Or drive your car to the city, steal someone else’s car for the dirty deed and then drive back to your car.
You can’t stop terrorism this way.
Maybe they don’t want to stop the terrorism.
Even the EU is trying to implement a more extensive surveillance state under the pretext of stopping terrorism.
