I think what Ford's Fields said was we can certainly build the high fe cars but consumers want Canyoneros. Also we want one national set of regs, none of this special stuff for Cali and elsewhere. I think the 1M jobs jobs jobs thing was B.S.
Those CAFE target fe numbers aren't just pulled out of a hat. A thorough engineering and economic analysis attempts to forecast what is reasonably attainable.
Let gas go to $6 and suddenly it all looks pretty good. Maybe the prediction is for expensive gas? Just because gas has been cheap lately doesn't mean it will be indefinitely. A national fleet composed of V8 4x4s would be pretty silly in an era of expensive fuel. Actually it's pretty damned silly anytime.
