Just like a flying ... Helicopter
Of course there are already plenty of flying taxis for the super-rich using helicopters.
And this gadget can do everything that a helicopter can. Except for range. And speed. And payload. When they talk about four passengers, they are probably thinking four times 100lb with no luggage.
Well, helicopters are difficult to fly, and expensive to run and maintain, so maybe electric quadcopters or similar designs will offer an advantage there, opening up the flying taxi market to the slightly less affluent. I.e., not just multi-millionaires but also TikTok influencers and the like.
