You're kinda right though op, we didn't see flying cars because it's been deemed too dangerous/difficult to implement (also hard to train for).
Flying bicycles are another thing we've not seen much of due it lack of demand.
We know how crazy loud aeroplanes can be, flying cars? 🤣🤣🤣 no we aren't there yet and that's so far away, not until we can fix the loudness of drones and planes then we can start dreaming.
I thought of this a few weeks ago .they could be made a lot quieter/smaller by having a container full of liquid helium that expands when the car wants to take off and compressed when it wants to land.
There'd be a lot less of a risk for wings/prepellars colliding and perhaps less energy used if something could deliver enough of a force to recompress the container and keep it compressed.
