The market would have brought about a natural improvement in overall fleet mileage with higher gas prices. Now we have the government screwing it all up and what we are going to get is crap little cars to meet an unrealistic goal and the US automakers probably going out of business since the majority of what they sell well are Trucks and SUV's
If we were going to have the government change it it should have been to move it up slightly rather than drastically. Enjoy the era of power while it lasts
