This is where the PAL_V flying car comes in. It is a gyro with folding blades and drives on the highway. Gyros are already FAA certificated and no problem there. New Hampshire has now approved it on their highways. It took 75 million dollars in development. Cost–2 seater $300,000- and 4-seater $600,000 If you are interested, I am a dealer in Arizona–send me an email for a picture. brunettoaviation@gmail.com
