In the USA you can keep it at your house if you wish, but you will only take off and land from an approved airfield, be that a grass strip or a paved runway. This sophisticated AirCar will not be permitted to take off, fly and land willy-nilly. There are safety regs that must be obeyed. I foresee the need for a pilot’s license exactly the same as for a Cessna 152 and up, with approved avionics, radios, etc. Not to mention that the machine itself will cost several hundred thousand dollar$. The barnstorming days of the Wrights or even Lindburgh are ancient history. The skies and airways are crowded. Anyone who flies anything beyond a motorized hang glider will need to have proven skills and abide by strict safety standards. Anything else would be pandemonium, with gerry-rigged contraptions falling out of the sky, causing bloody injuries and destroying property. Just my opinion as a former private pilot.
The concept of a flying car for the masses will never see the light of day!
Not in Alaska, nor in rural areas. :D
Not true at all you can do off airport takeoff and landing ops in VFR conditions to and from class G or E airspace no ATC is required for VFR only in IMC with IFR certified aircraft does an ATC flight plan need to be filed and clearances granted. The FAA has separate restrictions on when how and where a PPL licenced VFR pilot can operate the short version is other than to take off and land you cannot be closer than 500 feet from a structure or person on the ground. If you are landing on private property such as a grass field Bob’s your uncle same for take offs. Public roads are for emergency use only but a private drive would be perfectly fine. There is a fly in community a few miles from my land all the homes back up to a common grass area that’s mowed and maintained as a takeoff/landing area the garages open in the rear to access this landing area. I have done a number of off airport landing in rural Alaska, Montana, Wyoming and Idaho no better way to get to Elk or Bear country.
Here is some background on class G and E airspace.
