I mean I love the sci-finess of the concept also I doubt it'll ever "fly".

But I will bet money that we'll see self driving electric Ubers on the road before we see those air-taxis.

And it's going to be incredibly hard to compete with those. Especially as city will be becoming less crowded as more and more people realize they don't need a car anymore.

I live in Bangkok where Taxis are extremely cheap compared to owning a car. I would never bother getting my own car, it's just so convenient to let someone else drive in the city.
