Car designers love churning out funky concepts, then once the engineers and beancounters get hold of it something far more mundane gets spat out of the production line.
An autonomous aircraft takes a little more engineering than a 4-wheeler.
There is lot of air between a great idea and a working prototype, a bit like Mr Musk that comes up with hyperloop. pats himself on the back and the lobs it at engineers to try make it work.
