Criminals are often not the brightest sparks. My car was stolen last Friday night. It's on a car-share platform so the thief took the lockbox that's normally fitted to the window, bashed it open to get the key, and came back later for the vehicle. There is a very conspicuous warning on the lockbox that the car is fitted with two GPS units. When I first reported the theft, police said all they can do is wait for the car to show up and provide a report for insurance purposes. Then I checked the location via the car-share site. GPS updates were still working. When I called the police back to let them know I had a current location and could keep them updated in (almost) real time, it changed everything. Suddenly multiple cars were sent out while I kept reporting updates, and they managed to make an arrest within maybe 20 minutes. It's great to see how a little technology can give victims a taste of vigilantism without endangerment.
