It's not just "not super safe". It's actively dangerous. These things can straight-up mangle a person - at least ones big enough to carry tacos. Guess what happens when a little kid or a dog sees an RC helicopter flying around or landing - they run to it.
So are roads, yet we build them near homes. Children are just going to have to learn not to touch spinning blades like they learn not to run into traffic. And dogs will be dogs, I suppose.
This is an exceptionally low standard. Are unmanned flying taco deliveries one millionth the benefit towards society that roads are?
There is also an entire industry based on keeping children safe from everyday dangers. We have baby gates, plugs for electric outlet, fences for yards, childproof medicine caps, cabinet lock, etc. Exactly how are you keeping your child safe from the swarm of helicopters delivering tacos en masse to the park he's playing in? Do kids need to walk around in protective bubbles because the need to avoid waiting in line at Chipotle outweighs the need for safety?
