This is where a transponder on the drone will help. People could stop pointing at all drones and focus on the lone idiot drone operators.
I tend to agree - transponders on drones have a lot of benefits to include tracking with ADS-B equipped aircraft, and the ability for ATC to 'see' them and track their progress. Transponders have even become pretty darn small over the last few years.
The one issue with transponders is that there needs to be a closed-loop, non-hijackable way to change the code. The transponder code is what is assigned to you by ATC in order for them to better identify you. The codes can also signal things like emergency, communications failure, hijacking, or even just flying under "VFR" or visual flight rules.
Lets use the VFR example for drones: in theory all drones could squawk on a code, lets call it 0600. This code would tell ATC "drone aircraft, altitude, heading, type" and that would be immensely helpful for most of the country. But what happens when you receive a new code to squawk as part of an airspace authorization? I suppose in this case, you have to change it before the flight either with a manual input or by hard-wiring in with your computer.
But squawks are often changed in-flight. Lets say you have a drone in distress. You should squawk the emergency code so that ATC knows to vector aircraft around you (if needed because you're flying high or there are low-flying aircraft). This is where the current regulations start to interfere with transponders. Although they make transponders with a remote-changeable code, they aren't currently legal in the US because of security reasons. These reasons are that a bad guy or malicious actor could hijack the code for the aircraft and change it in some way as to cause harm to surrounding aircraft.
Until this issue is solved, either through regulation, technology, or some combination thereof, drones and transponders won't happen. Its only a matter of time though....and it will be a good day.
