You are delusional when you say its tough to make a case for flying cars.

The Airbus E-fan already exists.

http://www.airbusgroup.com/int/en/corporate-social-responsibility/airbus-e-fan-the-future-of-electric-aircraft.html

The Ehang 184 already exists.

http://www.ehang.com/ehang184

Advanced flight control systems already exist.

https://www.ted.com/talks/raffaello_d_andrea_the_astounding_athletic_power_of_quadcopters?language=en

Clearly flight on demand systems are here - not the future.  

Now, you can actually look at the engineering data from actual flying systems.  From that analysis we can say with certainty, the Airbus E-fan uses 1/5th the energy per kilometer than a typical motorcar.   The Ehang 184 uses 4/5th the energy per kilometer than a typical motorcar and is capable of point to point travel.  

Serious aerospace teams have melded the two together to give a point to point capability to an electric aircraft while reducing its energy cost per kilometre to 1/5th the energy of a typical motorcar - while maintaining higher speed.

http://www.nasa.gov/topics/technology/features/puffin.html
http://www.scientificamerican.com/article/nasa-one-man-stealth-plane/

EXISTING models are quieter than a motorcar and produce no exhaust in operation as a motorcar does, use less energy per unit distance than a motorcar does, travels 7x faster than a motorcar does.  

There is absolutely no basis for your delusion.  NONE.  

The Ehang 184 moves directly from point A to point B - requiring no ground based facilities at all.  No roads.  No airstrips.  Count the costs of road construction and maintenance, and you see why most under developed countries will NEVER have large numbers of automobiles, but are easily serviced by a modest number of drones.

Aircraft are not constrained to a 2D surface and so do not get involved in the same sort of overloaded situations common with terrestrial travel.  So, they're safer than motorcars too!

So please examine your crazy delusion and drop it.

I think you've just asserted that none of the many vehicles described
in this article ever actually existed in the real world.  You seem to
be wrong...

I'm talking with these folks about becoming a dealer here in New Zealand...

http://pal-v.com

In a country friendly to civil aviation and possessing a 100 kph (62 mph) speed limit, and anywhere I want to drive is less than 550 km (340 miles), the ability to fly directly to where I want to be at 180 kph (112 mph) and back - is a definite plus!  

So, I'm looking forward to it.  

I'm also looking at a boat/aircraft for use on the many lakes streams, bays and channels around these islands - but that's another technology - that pairs well with the auto/air combination here in NZ.

Hahahahaha!  No, I’m “asserting” that you apparently don’t know how 
to read the “Status” column in the list you have, with entries 
ranging from “Concept” to “Crashed”.  None are “Click to buy one” or 
“1% of pilots regularly use it”.

Pointing to experimental aircraft is like pointing to cold fusion.  
They are a *fiction* in the real world.  Your case is not made when 
you’re deliberately being intellectually dishonest like this.

Many experimental aircraft actually worked while cold fusion has never
been shown to work, so there is no comparison.

Utter nonsense.

As shown by the many flying cars made that have actually flown, they
are quite real and the lack of commercial success does not mean that
they did not or do not exist.

The one and only reason for the lack of a commercially successful
flying car is and always has been economics.

So your whole 'argument' amounts to a chicken/egg thing.  You said
there were no flying cars in the 'real world'.  Now you want to move
the goal posts.

Do you know the FAA definition of 'experimental aircraft'?  Speaking
of "deliberately being intellectually dishonest"...

No, I’m saying that just because someone is *trying* to make a 
thing happen doesn’t mean it has happened, or will happen.  The 
starting context for this is a space elevator, but it applies to 
many things *in the context of science fiction*.  Another fine 
example is 3D TV or holograms.  Yes, there are people trying to get 
there, but they don’t exist in *any* sense as their science fiction 
promise.  You are being intellectually dishonest when you pretend 
there is no difference.

No.  I know what I see on the road and in the air.  I do not see 
*any* flying cars anywhere I look.  The burden of evidence is on 
*you* to show they exist beyond some ill-conceived R&D efforts.

3D televisions can be purchased at Best Buy, Amazon, and many other
retailers.

You can buy greeting cards with holograms.

Have you been living in a cave?

Yep, living in a cave.

It appears you also have not seen any 3D televisons or holograms even
though such are fairly common these days.

Holograms is actually one of the worst cases.

It seems that very many SF authors simply do not understand
the properties of real holograms at all.

A hologram consists of an interference pattern.  When directed
light falls on that pattern, 3D objects can be seen.

One point that SF authors or directors routinely miss is that you
cannot see anything of the hologram if you are not looking at
the interference pattern.  A hologram cannot absorb, bend or
refract light anywhere else (so the Doctor from Voyager is out).

It is also not possible to have 3D projector that, simply by
projecting light, can make something appear in thin air that can
be viewed at an angle from the projector.  So, forget about R2D2
pojecting the picture of Princess Leia.

No, Jimp.  Flying cars were and are a good idea unless you think you
can just land anywhere you like.  If you fly a GA aircraft, what do
you do once you land it?

You are replying to someone else, not me.

Once you land the plane, you taxi to the tie down area, tie down and
secure the aircraft, then go see the FBO. There will quite often be
a dedicated phone to Enterprise. Don't forget to ask for your Aircraft
Owners and Pilots Association discount.

In the post 9/11 world there is yet another complicaton; all airports
have fences around the operating areas, which means if you are not
based at the airport and have the ability to open and close the gate,
you will have to find someone who does to let you on and off the airport
with a flying car.

Drive it away if you own it and you need an airfield.

Let it fly to its next pick up if its automated - after dropping you off precisely where you want to go.

Just the opposite!  If I can only fly between airports, why not just call 
it an airplane?  What actual problem does a “flying car” otherwise solve 
that make it such a fantastic machine to have?  What is the actual use 
case that demonstrates *any* added value?

Depends on the problem you’re looking to solve.  If it is to keep a 
vehicle in constant service, I’d say you’d fly it right back out to its 
next destination.  Same way it doesn’t make much sense to leave a 
self-driving car sitting in a parking lot doing nothing.

That is called an airline.

Assuming the self-driving car is owned by Uber and not an individual.

Only because that’s the known business model that works with the old 
technology.  Likewise, I’ve made the point that a “self-driving car” 
has existed for centuries; it is called a train.  Again, all I’m 
asking for is for the SF world to be fleshed out where it makes sense 
to have *your* kind of flying car.

Assuming nothing but a realistic universe.  Yes, I would agree that 
self-driving cars prompt a whole *slew* of changes that might lead to 
changing norms of car ownership.  Same goes for the mythical flying 
car, too, so I’m just looking for the proponents to do the leg work 
that shows they make sense in any sort of realistic universe.  
Because, from where I’m sitting, they’re just another dumb idea that
nobody really bothers to think through.

A train is not a car. Consult any dictionary.

The definition of flying car is universal and not mine alone.

Since I didn't say anything about self-driving cars I don't know what
you are agreeing with.

Flying cars are not mythical as many have been built.

What has not happened is they have never been a commercial success.

There is a big difference between not existing and not being a commercial
success.

The reason they have never been a commercial success is economics; too
few people have been historically willing to buy one for anyone to go
into production.

Whether or not YOU see any use for them is irrelevant.
