The other side is my own pet peeve: thinking that sci-fi authors were visionaries for putting something out there before anyone else makes it real. One reason we don't have flying cars could be battery tech, taking your example. There's a ton of cool shit happening in aviation as batteries improve.

Flying without lift from wings or like as people think of sci-fi flying cars isn't practical, unless we break the physics as we understand today. I honestly can't think of anything more wasteful than hovering flying car...

Even if you fix all the other problems with flying cars, you're not gonna fix the noise issue. They are simply too loud to use in populated areas.

"How many angry hornets does it sound like?"

"All of them."

I love flying car demo videos with dubbed-in music rather than live audio....

Firstly, I wouldn't be so sure about what future tech might bring. Perhaps if "flying cars" get closer to something consumers could use in a neighborhood, it will be profitable to look into and maybe something can be done about it.

Secondly, for many of the young men living near me, noise is more of a perk than an issue. You could probably sell them on the idea that the whole town gets to hear that they're rich enough to afford a flying car.
