Interesting, thanks for the correction.

I don't think the handover issue is a fundamental problem with the drones though. For example you could receive an automated phone call to let you know the package is hovering above your house. If you're ordering something to be delivered in 30 minutes you're probably going to be there to receive it.

But I still see theft in transit as an issue. The moral/mental threshold is surely much lower for shooting down a mechanical fly than it is for raiding a van.
