It certainly may be true that "the time is now to increase mpg for cars, trucks" (Opinion, Sept. 12). However, your continuing, now almost hysterical, rant for higher corporate average fuel economy standards is not the solution.
It's up to automakers to produce cars and trucks that customers will purchase within the overall market environment. At $3-a-gallon gasoline, many more people will purchase high-mileage vehicles than previously. Automakers do not need CAFE to figure out that their model mix must change.
But $3 gasoline is not a problem to many consumers, and they will continue their past buying patterns. Also, by its very name, CAFE is counterintuitive: "Corporate average fuel economy" dictates that all makers must produce either only fuel-efficient vehicles or an artificially balanced line in which enough high-mpg models are sold to offset low-mpg models.
With the increasing need for high-volume standardization, it may be more rational for some companies to produce only larger, higher-performance, luxury and sport models while other makers produce only fuel-efficient models. The market might actually prefer such an arrangement, but government-mandated CAFE laws make that impossible.
Oil is a commodity in limited supply with an increasing price. So is California real estate, but no government has yet mandated a household average resident head-count standard. The market rules, and I would have thought that you understood that fact.
