I think training similar for what commercial drone pilots require isn’t far fetched, however. A hobbyist probably doesn’t need to read aerospace maps, METAR reports, etc., but should be able to answer the safety questions with ease before they start flying their equipment.
I’ve held off on getting my Part 107 certification because I’m too lazy to drive to the testing center, but this shit isn’t rocket science and puts up a high enough barrier of entry to keep the skies reasonably safe.
I wish the FAA had gone this route first before debating potentially expensive electronics on every consumer drone, I think it’s going to hurt more than it helps.
