The point is that if someone is going to fly a drone in the middle of the road, then making more laws isn't going to stop them. People that do things like this have no regards to any laws because they dont feel that it applies to them. Condemning them only feeds into the enjoyment they got out of breaking the law in the first place. I think this was probably some kids monkeying around with the lack of adult supervision, but I wouldnt be surprised if it wasn't one of these stay at home youtube dads ether.
How about tuffer laws against parents that dont properly supervise their kids. More drone laws wont stop these situations from happening, it just adds more expense and burdens on people who do follow the laws.
