>permission from the town is no problem That may be true in a small number of very pro-technology cities in the US, but I think it's far from the case around the world in general.

Autonomous drone technology has been available for quite a while, and is used for use cases like the ones you describe (but usually on private property). The new thing here is drone racing - very high speed, high precision flying.
