Pie in the sky?
I certainly hope not, although as much as I would love to see us all flying through the air "Jetsons style" I think we're still a good few years away from a useful and affordable solution. This, as you say cannot lift two average size men and that does not account for briefcases, bags etc. making it an expensive toy.
Really it's just a plane that can be driven on the road rather than a viable flying car. I don't think a true flying car - which can carry four people (2 adults, 2 kids) plus light luggage, and will not cost hundreds of pounds/dollars in fuel every trip - is possible with the current propulsion technologies in use.
Good luck though.
