That, right there, is the key to our disagreement. You want everybody, who wish to fly a drone, to prove, they've "taken precautions".
I don't think this is as black and white as you seem to indicate. Nobody's stopping me from building a drone in my garage and even flying it out in a field, as long as I follow some reasonable restrictions that were setup based on experience with model airplanes. The restrictions are on commercial use, and the FAA is basically saying: these things are dangerous when you fly them over a population, and we need rules in place with proper safety procedures before it's allowed. That seems pretty reasonable to me. Yes, I wish they would hurry up. However, what are the chances that these drones are designed such that in the event of a failure, the likelihood of hurting someone on the ground is mitigated? Does every system have 1 or 2 backup systems? Doubtful. Has anyone done an analysis of how dangerous the impact will be? What's the likelihood of surviving a direct hit? What's the likelihood of it happening? Is there a safe reference design? Are there regulated auditors who can certify these designs against a published specification to certify them for flying over a population? Certainly when I build an industrial machine there are published standards regarding machine safety that I have to adhere to, and I must have the design stamped by a P.Eng. before the machine can be used in a production environment.
I'm all for this technology, but I know human nature when it comes to people willing to put other people in harm's way to make money. The FAA is right to ban these, for the moment. Amazon should be working with the FAA and other stakeholders to draft a proper set of rules to allow flying these things over a residential neighborhood. This is hardly unreasonable. The "anything goes" mentality is just BS.
