responding to a nasty gummint directive seeking something Good. The fuels..
Where what *they* want is the ... Baddest insolent chariot that keeps the profit-margin max -- next quarter.
(When first Euro cars hit the US and started taking sales in late '50s early 60s, the quip on campus was:
when Murica makes a 'small car' it will be the heaviest, lousiest handling gas-guzzling small car the world has ever seen.
Ayup, some thought the Thunderbird a 'sports car'... and so it went.

I'm still waiting for a Detroit reply to the NOVA special (with Click n'Clack for comic relief) wherein Amory Lovins showed his carbon fibre modules,
each liftable by a human and glued into place to form the next generation car -- while beating crash-test dynamics etc.
Exit, therefore: massive steel-sheet bending machines and much else that adds to expense but not performance. Carbon fibre is expensive.
Now. And what similar products might be developed that cost less? Doesn't matter to Detroit CIEIOS.
At least -- not yet, it seems. Murica runs on Redmond-logic: find a better solution out there?
Buy/or cheaper yet: bankrupt that company and kill the idea. Long enough..

But hey! maybe we Could grow up.
