Word to the media: don't bother us with this shit until they have a working idea on how to monitor and regulate the shit so we can all have flying cars and not just one dude's stupid prototype. The hard thing isn't making a car that can fly. That shit is relatively easy. The hard part is figuring out how air traffic would work if everyone was up there. It's already a PITA and there aren't a helluva lot of planes compared to cars.
If they're all automated and coordinating, NASA has put a lot of effort into researching how to coordinate a swarm of airborne agents with diverse goals.. I'd imagine that these prototypes have gotten further development and a reality-collision as drone systems have been deployed and evolving in the Ukrainian theatre. The tech for this might actually finally be ready.
