I like the cop gps…would there be a way to make a super cheap gps based tracker that you can stick on a cop car?
I say use a magnet or some really strong fast drying glue find a kid with some balls, and stick them onto the cop cars frame.
After a few months you should have most of the cop cars labeled, and they won’t even know. Once they do catch on, since they would be cheap to make, it won’t matter when they throw them out.
(I don’t think they would ever catch on though.)
