Still waiting for any serious attempt to get off fossil fuels. Oh well, there goes the planet.
I'm not necessarily opposed to something like that, but then we'll be getting back into the "you sold me unlimited internet but it's not really unlimited because even if I use it at 100% capacity I can't consume infinite bandwidth, so there is in fact a real limit"
Also, the real reality sucks. ;).
As someone who did a pilot's license, real flying is pretty complicated at the moment by the time you've checked 20 things, radioed air traffic control etc. To get a movie flying car like experience I think you'd need self driving car type AI to deal with that stuff. Which could happen before long.
Humans are too dumb to be able to drive cars safely, as evidenced by over a million people dying in traffic accidents each year. That the air travel industry has so little accidents is a miracle, and in big part owed to all those pesky and annoying regulations that can coordinate thousands of people on the same task and make them do their jobs right.
I believe that the class of people who complains in this case is rather disjoint from the class that wants less regulation.
Flying car now is a better idea, if they're automated. More complicated flight systems are no problem for software. And safety will be far better than humans. Though if we get fully automated roads/cars, the speed improvement might not be so big. (Automated roads might be able to go at what, 200Kph? More on highways?)
According to their specifications [1], it can do 6 km/l when flying, and 12 km/l on land. The specs they give aren't directly comparable sadly, so I had to do a short calculation to get the flying mileage (180 km/28 l), but it suggests that your 20x figure is one order of magnitude too high. The vehicle's range also suggests a 3x difference, not 20x.
Light aircraft do something like 20mpg for a Cessna 150. No worse than many SUVs. 100 mpg is possible http://www.treehugger.com/aviation/hypermiling-plane-gets-45...
Take a drone which can carry two people's weight and put a transparent box with a door on it. Add small wheels and some minimal parking capacity. Add a parachute for emergencies. (Note that there won't be a long educations for pilots. You just choose an address in Google Maps. If the drone can land vertically you might have to select a flat area at the destination, but it should be negotiated (along with parking fee) before going there.)
Instead of flying cars I'd rather have the cheap launch capacity of the Shuttle, which must have set some record when it was ~ two orders of a magnitude more expensive per pound than promised. :-( With so low launch costs we would finally get real giant space telescopes and an industrial infrastructure outside the atmosphere.
Military drones fly themselves already. There will be routing systems for drones when e.g. Amazon starts to deliver packets to the home. And so on.
(But not necessarily helicopter. Note the "If the drone can land vertically". You could do this with a drone air plane. If the transparent box (passenger compartment) is moved automatically to/from an automated taxi to a drone, you have a point-to-point taxi service anywhere.)
Edit: The next logical step is a trailer home with solar energy -- move it anywhere with a taxi large helicopter airlift. Drones deliver groceries, while you enjoy the view from your mountain top, far from any roads.
