If anything I'd think that drones would save lives on net. Right now we get our packages delivered via multiton diesel trucks that speed through neighborhoods as fast as they can manage. Sometimes people step in front of these vehicles and are maimed or killed. Some of these people are children. All so we can get our AirPods delivered on launch day.
Drones could be a substitute for many truck deliveries, but the FAA has banned such uses. This endangers more lives, creates more pollution, and increases delivery costs.
