Those human size autonomous quadcopter companies are all so optimistic about the future that they don't even realize how pie in the sky they are. Holy shit the business model on those is so crazy. Fly out to the suburbs and land autonomously in your back yard. Then it flies out and lands on the roof of your office, or at the airport, or wherever you want to go all controlled by your smartphone. Like these things are going to be flying in areas where only expert pilots would even consider in aircraft that are horrendously unstable and light and in close proximity to obstructions.

The videos always show some guy in a business suit flying some laser straight path right to the building, not being buffeted around by the wind reflected off of the buildings and one engine out from a pigeon that got sucked into the motor.
