Jackasses seem to keep ruining it for everyone. For example i was at an art show and it was pretty packed, some jackass drone operation was flying a larger model, around 4kg / 10 lbs or so, up and down the isles probably 15 feet over people's heads. It was large enough that a simple slip up, if not outright killing someone would have caused a few trips to the ER. It's that kind of jackassery that ruins it for everyone.
It's finally starting to be a greater danger to be injured by an idiot teenager looking for some hits on his youtube channel than being hit by a stray firework.
it is unlikely to be a teenager because large drones are very expensive. i find it more likely that an overconfident adult is going to hurt someone. but hey... i think there are some kids on your lawn, right over there!
It depends in where you live. Not far from here there are plenty of idiot teenagers that have affluenza. Although it is rather redundant to say idiot and teenager. Certainly I was an idiot at that age it's to be expected.
