Some people really think that each time energy costs double, I should cut my vehicle size in half. Nonsense. I'm a working man and need to transport not just myself, but heavy cargo and more than one person (flight crew). Tomorrow, I'll be moving a 400HZ power cart and 5 Ton (BTU capacity, not weight) aircraft air conditioner from FL to NY. There is no place in my world for such unsafe silliness.
In fact, there is a valid reason people purchase trucks and SUV's by the millions. Not the least of which is that cars have been legislated via CAFE rules, to be efficient and small, and therefore impractical.
