> I don't know why they don't just shoot a magnetic dart at the car with a gps tracker on it.
Hitting a car going 100mph with a magnetic dart that and getting it to hit on a metal part, not a window or trim, and specially a steel panel, is not easy at all.
This got me curious so I went out on the street and held a magnet to the front passenger door of the first 6 parked cars I came across. The magnet stuck to 4 of them. The ones it did not stick to are a Nissan Rogue and a Jeep Sahara 4xe.
