Much of it is simply intellectual. Most people really don’t think in three dimentions, and only after expensive training is one really good at it.

Perhaps if its fully automated, it would work. We’re then talking about massive bandwidth needed for the links between the massive computers needed to control the airplanes and the massive computers needed onboard the aircraft to insure highly dynamically unstable aircraft fly, with the levels of redundancy that the general public would require.

I disagree. This invention is as good as cellphones, and as with them, our fledgling teenagers will adopt and out-utilize and out-imagine us all. Once they’re available, all the most earnest well-meaning top-down Public Good ‘regulations’ will not avail against the freehand operators. As with AK-47s and computers, there will be shops everywhere turning out counterfeit illegal patent-busting copies, and the happy chaos in the skies is practically guaranteed. Perhaps every family should invest in a nice 12-gauge shotgun to defend hearth and home against these carplanes (and against the football-sized models which already exist, and have the ability to fly up to your upstairs window and broadcast TV images of your doings).
