This is absolutely an "I'll believe it when I see it." sort of thing. I've seen dozens of concepts like this only for none of them to materialize as they should. Here is an airplane in the shape of a car: https://www.youtube.com/watch?v=a2tDOYkFCYo that's essentially the closest we've gotten so far. https://www.forbes.com/sites/bradtempleton/2022/10/19/alef-reveals-prototypes-for-a-flying-car-thats-really-a-flying-car/?sh=6f454ddf26cf Is their prototype reveal which has more information than this fluff news piece.

That said, this has the potential to do what they say it does. The other argument against it is, I don't know if another lane in any dimension is going to help our traffic problem. Right now they are priced at 300k but that just means that extra lane is going to be limited until the vehicles are cheaper. Once the vehicles are cheaper we'll have the same problem with traffic but instead of a fender bender, it will be two planes colliding and falling to the ground, hitting anything in that falling path. Overall doesn't seem sustainable as trains/trams, and walkable cities.
