If you are a policeman who has installed a gps tracker on a criminal or
terrorists car, that jamming is a problem. If you are company owner
whose truck drivers are suspected of abandoning their trucks for an hour
or so to visit some well known ladies, that could be a problem. If you
put a gps tracker on you car to recover it if it gets stolen, that could
be a problem. If your car has something like OnStar, and you get into an
accident from which you would like help to be rescued, that jamming
could be a problem.
