Only government, which has a bottom-less pit of money upon which to draw, could affort a fleet of hybrids. If I can spend your money, I'll buy hybrids; with my money, I'll buy a conventional car.
Government's job is provide services at the most efficient cost! It is not to piss away taxpayer $$$ on Kook ideas. If a Honda Civic or Ford Focus is all that is needed and cost 8,000 less, then the gov't is to buy that car NOT a more expensive one. And wait till the repair bill comes in for all the new batteries at 80K miles on these boondogles.
Hybrids are only a stop gap measure until the fuel cell autos are available at reasonable cost.
These govt's should be going DIESEL. You get 30% more power out of a gallon of diesel than gas, and diesel takes less energy to produce.
My VW Jetta TDI gets 51-55mpg and my Cummins Dodge Ram gets 20mpg unloaded. This is where gov't needs to go for $$$ savings.
