content: My Uncle used to be in that when I was a boy in the 1970s. He would only fly them in parks that had a lot of open space and never at an airport or crowded area or near a house or business building. These Drones are quadracopters that are controlled with smart phone apps and can go anywhere. They have cameras on them and can record videos. They invade anyone's privacy. They can be flown near real helicopters and airplanes and cause damage when they hit.  There is also a problem of people using laser pointers on pilots of helicopters and airplanes so they can't see. All that has changed is the technology so it doesn't take skill and experience to fly them, now anyone can fly them and cause damage. There is a big reason why nobody invented the flying car yet, people already crash with regular cars and a flying car would make things worse.
