My opinion is that the vast majority of the issues are caused by people who buy a drone off the shelf and take it up as high as it can go on their first flight.
This move will help stop general folks who have no idea about the rules and regulations from flying where they should not.
It's not going to stop the folks that (arguably) should know better, but it's an exellent start.
But generally, I agree. An easy to circumvent lock seems like a good idea. Enough of an obstacle to block general population from doing their stupid things, while still allowing those who know what they're doing to exercise the full capabilities of the machine (taking the responsibility for eventual damage).
This is exactly it. I'm 1000% okay with this. I hope that the eventual DOT regulations are following this line of thought.
