I don't think we'll ever get flying cars the way people imagine them.
To stay in the air, you either need to push a lot of air down (like a helicopter or drone), or have wings and push a lot of air backwards (like an airplane).
The former allows you to hover, but is incredibly loud. The latter allows gliding, but requires a runway for takeoff/landing, not to mention a lot of lateral space for wings.
Unless we have a breakthrough discovery and find a way to create lift without requiring either speed or moving a ton of air, the sci-fi visions of flying cars will remain fiction.
there's also the issue of "chunks of metal above people's heads can drop out of the sky". Imagine flying car accidents being about as common as car accidents today. That would be untenable.
