Not going to name names but there are a bunch of flying car and "autonomous air taxi" startups trying to get to market right now. They're all going to get their PP slapped by the FAA the second they actually try to operate (a whole regulatory framework still needs to be created to make any of this remotely legal) but apparently it's enticing to the type of individuals comprising the investor class right now because they have at least some money.
Shrug...
