I thought a while ago that ham radio regulations might be a useful conceptual template and, as you say, that's what seems to be happening.

I imagine we'll see some pushback on the requirements for getting certified (e.g. background check) but that's quibbling at the margins.

I also imagine that some won't like the prohibition on autonomous operation outside line of sight. But that seems a reasonable restriction to me if we're heading toward a spot where there are potentially lots of drones flying around.
