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.

"All of them."

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