You have to remember that the guys designing and marketing vehicles are also driving them....and most of them can afford to drive 'almost' anything they wish....so it's likely that production of SUVs and such is not totally controlled by 'normal' consumer wishes.

   I really doubt the masses of folks picketed G.M. and Ford, demanding gas-guzzling, polluting monsters. We really need stronger regulations about fuel economy and vehicle size to gradually bring down the total use of fossil fuels, aiming toward alternate ways of powering vehicles. I am not sure price of fuel will do it.
