The CAFE bugs the crap out of me. As some of you may know, I'm a big E85 flag waver. I talk about E85 as much as possible and try to share information or learn information at all times. Now the CAFE has a credit that increases the MPG for flexfuel cars by the DIFFERENCE in rated MPG(1/3 based on BTU content). The EPA is legally prohibited from testing cars with any Ethanol and instead uses the BTU differences. Considering GM and some other manufacturers were advertising near Gasoline MPG there is a disconnect in this methodology. The end result is that the most common flexfuelvehicles(FFVs) are gas guzzlers like the Chevy Tahoe, F-150 with the v8, and some midsize cars but only with the v6! As an enthusiast, that really pisses me off. These cars get 15 maybe 25 for the midsize and then they get 10 or even 18 MPG on E85, respectively. 99% of people that drive them will never use E85. Most of these people will never see an E85 pump even if they drove by one everyday. And even fewer actually know anything about it except what they hear from friends/family and mainstream news. Where on the other hand, myself I'd drive out of my way to get some E85.
This is just an example:
