If a flying car is invented, how will the "air road" system work?

I would imagine it'd be regulated much like the FAA regulates aircraft travel. There'd be designated "lanes" (likely unmarked, existing virtually and tracked by GPS-esque equipment). I would point to The Fifth Element and Star Wars: Episode II as two movies showcasing examples of how this may work.

Dude! It HAS been invented! The Skycar Moller International has developed the first and only feasible, personally affordable, personal vertical takeoff and landing (VTOL) vehicle the world has ever seen. You've always known it was just a matter of time before the world demanded some kind of flying machine which would replace the automobile. Of course, this machine would have to be capable of VTOL, be easy to maintain, cost effective and reliable. Well, we at Moller International believe we have come up with the solution. That solution is the volantor named M400 Skycar. Let's compare the M400 Skycar with what's available now, the automobile. Take the most technologically advanced automobile, the Ferrari, Porsche, Maserati, Lamborgini, or the more affordable Acura, Accord, or the like. It seems like all of the manufacturers of these cars are touting the new and greatly improved "aerodynamics" of their cars. Those in the aerospace industry have been dealing with aerodynamics from the start. In the auto industry they boast of aerodynamics, performance tuned wide track suspensions, electronic ignition and fuel injection systems, computer controllers, and the list goes on. What good does all this "advanced engineering" do for you when the speed limit is around 60 MPH and you are stuck on crowded freeways anyway? Can any automobile give you this scenario? From your garage to your destination, the M400 Skycar can cruise comfortably at 275 MPH (maximum speed of 375 MPH) and achieve up to 20 miles per gallon on clean burning, ethanol fuel. No traffic, no red lights, no speeding tickets. Just quiet direct transportation from point A to point B in a fraction of the time. Three dimensional mobility in place of two dimensional immobility. No matter how you look at it the automobile is only an interim step on our evolutionary path to independence from gravity. That's all it will ever be. Moller International's M400 Skycar volantor is the next step.

Did you see Back to the Future part 2? There are roads going in the air everywhere. It's a great question. I think the best way would just be a different direction at a different altitude. So everyone at 100 feet would all be going east. Sounds good to me!

Just like on the "Jetsons"...

ill give u a hint Fifth Element its an wickedawesome movie

More than likely a "flying car" would be controlled by GPS and a WIFI interface. Today's small airplanes are so much easier to fly with moving map GPS - this device allows the pilot to know within roughly 5 square feet of where they are in the air. Altitude, direction, speed, and a color graphic map is displayed where they are geographically. When WIFI is expanded nationally - beyond the local coffee houses and occasional bars and other private providers there will be a very effective way to control location and direction. This will allow virtually unlimited vehicles to share the airspace as the WIFI will be able to know where each vehicle will be by the millisecond. There have been "sky-ways" for many years that pilots have used to navigate long distances via radio signals. Now that GPS allows a very direct root without fear of loosing your guidance these sky-ways do not have the same necessity.

dude, don't worry about it

There's no way. Air traffic controllers have enough trouble as it is. Minor accidents, which are common on the ground, would almost always be fatal in the air. And what about drinking and flying? People who party and fly would surely kill themselves. Jeez, the more I think about it, the more it seems to suck. I hope it never happens.

good question!mabye cars will not be allowed to fly near airports so that way planes wont get in the way of the flying cars.
