Well there's a whole bunch of reasons:
(1) It's MUCH MUCH MUCH (is that enough MUCHes?) more hazardious than Gasoline.
     Remember that you're going to have grade school dropouts pumping this
     stuff into your car.
(2) It's about 4 times as bulky as the energy equivalent ammount of gasoline.
     Most people would not appreciate having to fill their tank with $10/Gal
     LH2 every 50-100 miles.  Not to mention the insulation on your tank to
     keep it from evaporating.
(3) It's much more expensive to make.
    (a)extraction from H2O (about 50% efficency?)
    (b)Cooling it to (whatever degrees K 10? 20?).
	Totally lost energy here (it's not useable to make your car go).
    (c)Keeping it COLD.

Ah! yes, the famous Quarterly Report syndrome.

I suspect that some people would be happy to supress it (if it were
genuiner), but somehow I just can't see it as a real item.
