People including those in Washington do not understand there is a
fixed amount of energy in the Carbon bond. When the Carbon
molecule is oxidized it release a known amount of energy that can
be calculated. (This energy can be found in any Handbook of
Engineering, Physics, or Chemistry and probably hundreds of sites
online) Regardless of what you do, you can only recover 100% of
this energy. Hence with cars to get higher miles per gallon you
have to reduce the size of the car. A roller skate should be able
to get a couple of hundred miles per gallon.

Like Bigfoot, I have heard of the supper carburetor for years, but
it still is not real.

While any given fuel does in deed only has a fixed amount of stored
energy reducing the size of the vehicle is not the only way to
increase gas mileage. Simple engine tweaks can do this, advancing
the ignition timing will do this. I currently have a heavier,
taller truck with an engine that produces approximately 50% more
horse power than my previous truck. It gets at least the same,
often better gas mileage than the older model did when it was the
same age.
It is simply a matter of getting more out of the fuel burn than
what
has been gotten in the past. Some engines burn fuel more
efficiently than others. Because most gasoline burning engines do
not do not get 100% return on the fuel that they burn they can be
improved to do better.
With the common day usage of on board computers and fuel injectors
gas mileage has improved dramatically over the last 30 years. You
can look as fuel injectors as the today's "super carburetor".

While it is true that fuel mileage has improved over the last few
years, Ford's Corporate Average Fuel Economy for the whole fleet is
the same as it was in 1919 with the model "T" - aprox 21MPG US.

And of course the Model T is capable of highway speeds and passes all
Federally mandated safety and emissions regulations.

Hint, Congress took gas mileage out of the auto manufacturers hands
years ago. They build to the regulations. If you don't like the
regulations, take it up with Congress.
