I haven't researched CAFE standards, CARB regulations, etc ... much and don't plan to. CAFE standards dictate that mfr. fleet have a certain average MPG rating, right? But, there is no obligation for the mfr. to sell a certain number high MPG cars, correct?
Incorrect. A manufacturer's CAFE is based on vehicles sold. Corporate Average Fuel Economy - Wikipedia, the free encyclopedia
"Nevertheless, the on-road vehicle fleets in the United States and Canada have the lowest overall average fuel economy among first world nations: 25 miles per US gallon (9.4 l/100 km) in the United States, versus 45 miles per US gallon (5.2 l/100 km) in the European Union and higher in Japan (2008)" "...Similarly, the law of supply and demand predicts that due to the United States' large percentage consumption of the world's oil supply, that increasing fuel economy would drive down the gasoline prices that U.S. consumers would otherwise have to pay. Reductions in petroleum demand in the United States helped create the collapse of OPEC market power in 1986."
