I've never owned a quadcopter, but have often thought of getting one. I work in the remote robotics industry and have been a fan of quadcopters, FPV and personal "drones" for years. That may change, though, if what I experienced yesterday is what we can expect in the future.
My wife and I were at the beach most of the day yesterday. There were probably a hundred other people in our small area, mostly families with kids. People had their awnings set up, bar-b-ques grilling, and kids running around just having fun. About mid afternoon a fellow showed up with a DJI Phantom (I recognized it because I often thought of buying one) and full FPV gear, not 10 feet from where my wife and I were, and not more than 30 feet from all the kids running around. He then launched and flew the drone up and down the beach, sometimes hovering over people, sometimes flying over boats and paddleboards that were passing by.
While I was in the water, his drone buzzed over my head, hovering maybe 5 feet away from me and stayed there. Just out of reach but definitely "studying me" like a buzzing giant mosquito. It was my first experience like this and I gotta tell you, it was creepy. I don't know this guy. I don't know his flying skills. I don't know how well he maintains his equipment. I don't know if he's shooting video of me and, if he is, what he plans on doing with that video. Is he a convict? Is he a child molester? I know nothing about this guy who is flying his quad just feet above me and is watching me so intently. The one thing I did know was that this guy's drone was invading my space and my privacy. He was watching (and probably videoing me) and I didn't like it. And I'm a guy, I can only imagine how I would have felt if I were a woman. Or a parent watching this drone hover over my small child. In that brief moment my feelings about personal drones reversed 180 degrees.
If what I just witnessed is the future of the technology, where people no can no longer live with any degree of privacy or space, I, for one, can no longer support it.
