Everyone is committed to being green as long as their lifestyle isn’t inconvenienced and they have the funds to buy the green equivalent technology.
It's also easier to avoid pedestrians as most can't fly.
It also could save on gas and energy as you can go directly as a bird flies to your destination instead of taking 20 minutes it takes 3.
Of course this would be a huge infrastructure ordeal as well probably and require a damn good system as you don't want vehicles landing on houses all over the place, but it'd be amazing for people with long commutes.
You could probably have airbuses that pick up like 30 people say in a small town and fly them to the city to be delivered individually by smaller vehicles locally. What took 45 minutes, now maybe takes 15.
These would be better if maybe electric with gas as an emergency backup system, and then just have good batteries and solar power fuel most trips.
Sounds somewhat authoritarian to impose your idea of the 'future' to inconvenience a large number of people.
There are a lot of great things about cities but you are dependent on other people for everything in your life, and it can go sideways incredibly fast. I.e the energy situation in Europe, or with COVID-19. Personally I don’t know how it’s not obvious to the millions of people who live in places like that.
This is everywhere true past, present and future. I would argue your small suburb gives you an illusion that isn't true.
This to say: the future is having cars removed from cities entirely. Focusing on self-driving technology, or on electric cars as if they're going to "save the planet", is entirely the wrong direction imo.
