I agree with the general premise that flying cars are not a good idea in the near future, but I strongly disagree with your point.
1st) "fundamental laws of physics rather than moore's law" is a great analogy since people over time have continually cited physics as what will stop Moore's law. Some argue that it has in recent years done just that.
2nd) Like smartphones, the technology to build flying cars has evolved and will continue to evolve. I'm not an expert on aircraft or cars, but I can think of some areas that will make this easier right away. A) by moving all controls to fly/drive by wire, we can reduce weight, B) Materials technology has improved dramtically. C) Battery technology has improved. Maybe not for flying, but for systems. D) Weight can be further reduced by having all controls in one small computer which will eventually be the size of a smart phone instead of the size of a desktop, E) Fuel economy is improving in both cars and airplanes.
But... Here is what I think can really make it happen, and what will make it happen. When cars and planes can both fly themselves with full automatition from point to point without pilot intervention, we will see flying cars. The reason stems from the fundamental problem that 99% of people don't know how to fly, and of those that do, only a small percentage can fly, afford and want to own a car/plane.
I don't know anyone who wouldn't be interested in hoping in a fully automated vehicle which would fly them from point to point at 500 mph. You could work 250 miles away from where you live.

It will happen, just not for a long time.
