Are the ladies impressed by old, married men with receding hairlines and Ferrari jet packs?
However, I'd settle for a road car with a Mr. Fusion that travels in time and runs on banana peels.
If a practical way CAN be found to do such manipulations, it could mean a great deal more than just flying cars and personal flight packs.
My guess: No more than another two centuries, assuming we don't wipe ourselves and the planet out in the interim. See you in the next lifetime! ;-)
Sorry for being such a "Debbie Downer", but I can't stand irresponsible drivers, tailgaters, rubberneckers, non-turn signalers, etc.
At least Jetpacks would be great in the same way that... almost like motorcycles in the air. Sure, you can still hurt yourself, or others, but it's less likely. And just like motorcycles, I'd like to see less people qualified to fly.
A flying car is a disaster waiting to happen. Small fender benders happen all the time on the streets... and people have been known to crash their car into people's houses and backyards. The last thing I want to see if someone's car falling from the sky due to bad maintenance through someone's roof.
I still think the focus in cars should be making them more efficient rather than something like flight. I just wish America wasn't so obsessed with driving lifted trucks, "ricing" out their cars to get their Honda Civic two more horsepower, and just plain driving fast.
Maybe an Iron-Man-ish suit would be better? Well, at least for the military/ law enforcement. And from what I've seen and read, it's been in development for decades.
Not only would a flying car be more fun to use, but it's also alot safer.
