I find it interesting that the question is "why don't they use drones". My question is: why so much air surveillance? I live in Germany. The only times I hear a helicopter is if someone is being rescued or if someones missing. I rarely see them at all.

There are high speed police chases (100mph+) in Los Angeles — no exaggeration — on an almost daily basis. Air support is the primary defense tool for law enforcement.

It's so bad that the local TV stations have their own choppers and a dedicated on-screen UI tailored for the chases with GPS-based tracking and speed.

If you're lucky you can catch one of the many YouTube live streams. Here's one from....two days ago: https://www.youtube.com/live/uGiJU-FlpdE

They get away from time to time from the airship. Two in one week this past august and I don't think they ever caught the suspects. One drove under an overpass and fled on foot, the other entered LAX airspace which requires waiting on clearance from ATC and got away somehow after that. 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.

There's a lot more aluminum than steel on car exteriors these days.

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.

Decided to scratch up some peoples' clear coats for a little science experiment?

Could I have damaged the cars even though I saw no signs of damage?

It would be nice if someone else with knowledge would chime in here. If this damages cars, then I want to know, so I can stop doing it in the future.

As long as the car is dirty, then contact with it can damage the top coat. This is a lot more true if you need to drag or scrape the magnet to remove it.
