Unless Obama can find a way to ramp up the price of gasoline soon, the near term sales of the many new B-cars are not going to be pretty, and fleet fuel economy improvements are going to be small.
Let's face it, Americans don't want little cars. They want cheap gas and large cars. I can't wait for the public reaction when the 36mpg CAFE regulations force people to look at B-cars, or pay a premium for larger vehicles.
