They are all very pretty, by that I mean this concept and the many other flying car concepts that have come, gone and are still under development with the promise of "in just a few years", which they have been saying since the 1970's and possibly earlier.
The main barrier still seems to be regulations and safety, so it still is a case of wait and see. It's still too early I think for flying cars for the masses, we are still working on self-drive for our ground vehicles (and that is a mission to get through the safety red tape for adoption).
People today have a hard enough time controlling their vehicles when they are restricted to specific roads and highways. I can't imagine the skies ever being open to the general public for personal transportation (beyond what they are for private pilots today). Air traffic control is not trivial as it is. Unless all the flying cars are on "autopilots" or some centralized, coordinated control, you'd have people all over the place with utter chaos. The smooth flows you see in the Jetsons and sci-fi flicks just don't happen on their own. Me, I'll stick to the ground.

"In full-scale Puffin will be 3.5 meters long, weighing 180 kg, including batteries and have a wingspan of 4.1 meters.
Propellers measuring 2.3 meters in diameter and will be driven by electric motors at about 45 kilowatts. They should give the plane a top speed of 480 kilometers per hour while cruising speed down to 240 kilometers per hour. With batteries weighing 45 kg will be level in the air about 20 minutes, and traveled to 80 kilometer.The researchers believe that the plane is able to rise to over 9 000 meters before the batteries run out and it is time for the landing.
