Re: Not just the US
"because of the visual reference condition"
As a part time low end hobbyist pilot (as in the type that uses WiFi and literally can't go much further than 40m in any direction; and only flies for about eight minutes at a time), it's actually pretty hard to keep the thing pointing in the right direction when you can see it. I've not flown at night with the drone more than a couple of metres away. I wouldn't want to try. Sure, moonlight shots are nice, but far too many trees around...
I can imagine things would be better with a good FPV setup to see what the drone sees, but on the flip side, if you're looking at what the drone sees you're not looking at the drone itself, making it easy to miss certain things like the bloody big helicopter just abo...oh crap...
