I live in a pop 200k city, hospital copters are a daily occurrence. Police? Never seen one, Hamburg, one of our biggest cities, apparently has 3.

Same for me. I live in a pop 1M city in America. Hospital choppers are fairly common. Police choppers rare.

Also, according to the tracker, there's only one airborne in LA right now, and it is a pretty large city. It's close to 100x bigger than a 200k city.
