Lots of people rely on GPS systems to help them get where their going and espically in their vehicles. My husband has GPS software for his laptop so we just hook up his laptop into his truck when we’re going on a roadtrip. If you’re trying to keep track of a vehicle though then the gps tracking would be superb to keep an eye on someone. I’ve seen quite a few shows where the parents keep an eye on their teenagers with the gps tracking. Keep track of someone today!
