lem0n, it was a joke. lol?
Actually, we have some cars like the Ford
Focus that can get 35-40 mpg, but we have to go foreign to get better mpg than that, like VW. 50 mpg diesel.
Here in KS, we had some FFVs running ethanol. Ethanol came from just across the state line, amd was government subsidized, so it was cheap, but it was an alcohol and thus cleaned out your gas tank and dumped the sludge into your engine, so the specialization necessary to make it work made it quite unpopular.
