OT: Has it ever occured to anyone that human-drived cars are the C of human transport ? Very many people die in communications accidents. Airplane travel may be safer per unit of distance, but NOT for unit of time spent in a vehicle. Human brains are not effective at 3D navigation. I think this is the real reason we won't see flying cars: because it makes an already dangerous activity an order of magnitude more dangerous. The only way I can imagine flying cars working is with software-assisted flight. Software would need to take over a big fraction or even entirety of the task.
