Long story short, It's the FAA's fault. Initially they said, "no, you can't do that" because there are no regulations for that. With pressure from companies, the FAA took years to create the rules to make drone deliveries legal. Finally there is some regulatory framework.
Drones have to be specifically designed and manufactured to pass the FAA's certification program. We've all seen capable drones from Amazon's marketing, but does it please the FAA? A drone can't do the job until the FAA signs off on that make/model. It's not easy to do and requires developing a craft with all sorts of safety features.
Companies are making progress, and I think the most insightful videos to watch on the topic come from Zipline. They're already operating in Rwanda with support from their government. They have a streamlined service and make 100s of deliveries per day.
To be fair, this sounds like the FAA is doing its job. Tiny consumer drones are one thing, but if there are going to be fleets of drones carrying packages all over my city, I'll take a slow and thorough FAA over move fast and break things.
That's the stat for all cars and trucks, but drone delivery isn't going to get commuters off the road. How many deaths are due to package delivery vehicles? More specifically, how many are due to the vehicles that will actually be replaced by drones?
That's the number to beat, and even a single collision with an airplane would most likely make up the yearly allotment before we even get into "package falls on someone's head", "drone runs out of battery over the freeway", and all the other failure modes a drone has.
That's why it's important to regularize drone traffic before it get out of hand. Safe flyways to get to neighborhoods. Delivery routes that find residential homes less busy (e.g. when school is in session).
On the subject of vehicles-causing-accidents, it's possible delivery trucks trying to beat a deadline may be over-represented in statistics. Speeding, driving aggressively, parking all over the place. So there's that.
Drones are point to point delivery, which is why they're currently used for transporting high priority items like cooked food and blood transfusions. If drones were legalized in more places, they'd substitute for quick trips to the store. This would be safer for everyone involved and reduce pollution.
Planes fly at much higher altitudes than delivery drones, so the only collision worries would be near airports. The FAA already bans drones near airports and requires special authorization to fly a drone within miles of major airports. Even if you get approval, you can't exceed 400 feet above ground level.
Of course not, but drones substitute for more than just delivery drivers, and delivery drivers do run over people regularly. Searching for terms like "fedex driver crash" gets you plenty of crashes and a decent number of deaths.[1] The most common casualties seem to be the drivers themselves and dogs. Most deaths are ruled accidental, but around once a year a delivery driver is charged with homicide for killing people with their truck.[2][3] In cases where an unsupervised child is killed, the blame is usually placed on the parents rather than the driver.[4]
If you're worried about delivery drones flying over neighborhoods, you should be even more worried about multi-ton delivery trucks barreling through places where kids play.
Good. Without their careful and considered work, the US skies would experience it's own tragedy of the commons. There's a reason air travel is so damn safe, and it's not because private companies were left to their own devices.
"The Air Commerce Act of May 20, 1926, is the cornerstone of the U.S. federal government's regulation of civil aviation. This landmark legislation was passed at the urging of the aviation industry, whose leaders believed the airplane could not reach its full commercial potential without federal action to improve and maintain safety standards. "
Maybe people were smarter in the '20s, maybe they were hoping for regulatory capture? Not sure, but obviously it's a good thing...
That quote does not disagree with OP at all. It says that the aviation industry itself determined that they should not be "left to their own devices" (OP's words) and asked for federal regulation.
"It's the FAA's fault" makes it sound like that's a bad thing. I think it's good that the FAA took time to create meaningful regulations and that somebody hasn't been able to just slap something together and be able to pass them.
Zipline's work in Rwanda is really inspiring. I love that they are doing real good in the world first and can leverage that to grow their commercial business.
I imagine it depends on the size of delivery. Even with extremely good roads, zipline would probably be faster (I can't imagine that flying in a straight line is _ever_ slower than driving), just lower bandwidth. Single small package? Zipline is probably much faster. Many and/or large packages? Driving is almost certainly faster. Good roads don't change this basic fact, they just change the break even point.
