i hate to say it but my 98 civic gets 30 to the gallon. It makes me sick when i hear Chevy say "super fuel efficient" and then "31 mpg". There has been virtually zero progress in 10 years...actually more like 20.
A huge jump in fleet mpg standards would do exactly what the article says, but we do stand to gain from incrementally raising fleet standards. The car companies would even have a huge head start considering how people are buying more fuel efficient cars already. Up it .5-1 mpg each year until you get to 40 mpg. That is certainly not out of the question. Most of the technology is already out there and would not be super expensive to produce.
This is the main key that the environmentalists will have to concede on for a while. Do not change the emmisions standards at all for a while. Let them lag behind while we focus on mpg. I think that'd be a plan that most would support.
