The autonomy video said what it intended to do but (as far I could see) not how it was going to do it. It talks about standard routes and automated collision avoidance and interface with ATC. But self driving cars seem to be taking a lot longer to get certified than earlier expectations and they seem an order of magnitude easier and less dangerous. For instance what happens in case of technical failure say an electrical glitch? I am sure all of this is solvable, just that when you factor in aviation and other authorities this is going to take a very long time till meaningful implementation.
