The real issue is that flying cars need a lot more energy since they need to stay up in the air as well as move forwards, and the oil crisis quickly put an end to that kind of per-person energy consumption being realistic.
- Sohcahtoa82 4y agoI 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.
- bobthepanda 4y agothere'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.
