If you search on "retrofit" in the document, you will see that it refers to 
retrofit from
gasoline to dedicated LPG or natural gas vehicles. Not to
"GEM"  (gasoline/ethanol/methanol) flexibility.

LPG is a limited fuel. Compressed Natural Gas is VERY strongly favored
by natural gas lobbies -- but it is far more expensive either as a new
option or as a retrofit than GEM in new vehicles.

There is a pervasive "chicken and egg" problem in trying to change fuels.
Not so many people would buy dedicated natural gas vehicles today,
in the absence of natural gas in the gas station. And you
can't put natural gas effectively in the same tank as gasoline.

Still, I would propose a new law that would let the consumer choose.
Only those cars which HAVE gasoline tanks and an ability to burn gasoline
would be required to have tanks strong enough to also hold ethanol or methanol,
and engines capable of any mix. That's feasible in 2-4 years (2 if we do it 
for ALL new cars.

If GEM flexibility were a fact TODAY all across the US -- the incentive 
would build up
to the private sector to supply that alcohol fuel. There are many sources,
and many new technologies. ONCE methanol is available enough...
even in local areas.. it becomes much more realistic to talk about selling
fuel cell vehicles which use methanol as a"hydrogen carrier."
(Small scale efficient converters from methanol to hydrogen have been 
proven for decades --
but from gasoline or natural gas, it really does not compute, and DOE has 
recently given up
even trying. Losses in storing hydrogen AS HYDROGEN, and in getting 
hydrogen to a car nozzle,
far exceed the losses in the small-scale reformers!)
That's our best hope of getting to fuel cell cars before it is too late.
