Flying cars face a moving bar of regulatory requirements.
So do airliners. Yet they exist. You conveniently blame regulations when time has shown over and over that when there is an actual technology that exists, regulations will change.
Your refusal to acknowledge real-world limits and incapacity to imagine constraints (for example, imagine the flying debris from millions of flying cars taking off and landing all the time), is indicative of a wide-eyed daydreamer. This is an engineering forum.
Where's the engineering?
You won't get flying cars. You won't get practical fusion power, or a shiny happy society of technological abundance. We could have done it by now, yet we didn't.
That's all there is to it. It's called "reality". Give it a try sometime. Then you'll see it has nothing to do with vitriol, or any of the emotional outrage you guys spew.
It's very, very simple: 92 stable elements, most of which are either useless or dangerous. Four fundamental forces, only one of which we can claim to control somewhat, and two others we can sometimes tickle.
That's it. No Star Trek, no Space Elevators, no Moon colonies, no brave Martian homesteaders, no warp drive, no replicators, hell we couldn't even manage a leisure society with minimum guaranteed conditions for everyone because we're such stupid animals we can't tolerate someone doing nothing all day even though we're surrounded by so much technology we think we'll colonize the universe.
I think you guys watched a bit too much of this
as kids.
