I don’t know how they can account for a drone randomly failing and dropping out of the sky? It’s not a matter if it’s going to happen, but a matter of when it happens. What happens if it landing on a car while someone is driving? What happens if it lands on person just going about their day? I don’t see any of this being worth the risk.
I see the targeted locations are considered the type to be open land regions, but that doesn’t eliminate obvious risk.
