If by measure you mean "have the public policy discussion using specific details" then sure of course that's the best/only way to do it.
But if you mean we have to let the low sky fill and noise level ramp first, then absolutely not. We don't have to see it to understand the impacts.
Having airplanes at 30,000 feet and gated by a very finite number of runways that can launch at most a specific number of flights per hour is one thing. But allowing every warehouse to launch as many drones per second as they'd like all flying at a few hundred feet where they will be hard to miss either visually or audibly, is an entirely different concept. In my book that's something that needs to be stopped before it starts. I'm someone who both shops online frequently and values the beautiful environment I live in, and if what's on the table is I can save a few bucks and some wait time from each order, I'd much prefer to keep the beautiful environment and not get that shipping benefit.
Nobody proposed allowing “every warehouse to launch as many drones per second as they'd like.”
You have invented an airborne Wild West and then quite understandably concluded that the airborne Wild West sounds unpleasant. Did you actually read the article and look into how these operations are regulated, or did you just knee jerk your way to the keyboard and start typing?
These are regulated commercial aircraft operations. Amazon needs FAA certification, approved operating areas, airspace authorization, safety procedures, collision-avoidance planning and environmental review. The FAA is already examining noise and community impact before these operations expand.
So yes, by “measure it,” I mean exactly that: determine actual noise levels, flight density, routes, safety record and community impact, then regulate accordingly.
What I don't mean is, “release 75,000 drones at dawn and we'll see who survives.”
And there's another rather large assumption hiding in your argument: that every online order suddenly becomes a drone delivery. It won't. These aircraft have payload, range, weather and operational limitations. They're aimed at a subset of last-mile deliveries, not replacing UPS trucks with a permanent metallic cloud.
If actual operations demonstrate that 500 flights over one neighborhood every afternoon sound like an enormous electric beehive, regulate the routes, hours or flight density.
Perfectly reasonable.
But “stop it before it starts because I can already imagine what it will be like” isn't measuring the tradeoff.
That's announcing the conclusion before collecting the evidence.
At that point we're no longer doing public policy.
We're reviewing a movie trailer.
