Flying cars
I too was incensed for decades about the lack of flying cars (and jet backpacks).
But I now understand the hidden assumptions which keep us grounded.
We incorrectly assumed that our righteous need for jet backpacks would cause the relevant laws of physics to suspend themselves in recognition of our Destiny in the Sky.
The actual situation is that we have helicopters, which already do everything we want a flying car to do except drive on a road. (Driving a helicopter on the road is just an engineering problem.)
Helicopters are loud, dangerous, and very expensive. Practical helicopter technology began around 1900, and since then titanic amounts of engineering effort have been expended in a effort to make helicopters less deafening, less lethal, and less unaffordable. Chances are they are as quiet, safe, and cheap as they are going to get.
What about parking? You've seen helipads? You see the space requirements for landing and takeoff. Where will we store the tens of millions of helicopters which hurt our ears, charge our fears, and empty our coffers?
Even if we could afford helicopters... would you really want to be *up the sky* in your flying car *with all those other people in their very loud flying cars*?
This is all idle chatter. We can't afford it and short of a world-changing source of cheap energy we're not ever going to afford it, so let's forget about flying cars and instead go hang gliding or hot air ballooning so weekend, get it out of our systems.
(No, I can't lie to you: I will continue to dream about flying.)
