I dont even know where to start with this one.
It really boggles my mind sometimes how much I've changed my driving habits. I ride with relatives once in a while (my girlfriend is also a hyper-miler) and am appalled at how inefficiently they drive. My mom has a ridgeline with a gauge right on the dash saying she's getting 16.5mpg almost all the time. She pretends like it's not even there!
Once you've become a hypermiler, it seems those around you adopt some of the driving habits and skew mpg estimates. Maybe it's just me, but I drive so much differently than I did last year that I don't even remember how bad it was.
The 1983 fuel economy estimates are CAFE fuel economy numbers, so the "converter" you all are talking about wouldn't work because it's suppose to convert 1985-2007 fuel economy estimates to 2008 estimates.. 1985-2007 fuel economy estimates are already adjusted from the CAFE estimates.. If you find fuel economy numbers for a vehicle pre 1984, those are likely cafe fuel economy estimates which while are still in use today, you won't find them on the Monroney sticker or advertised anywhere. You have to specifically look for the cafe fuel economy numbers.
Yeah, they tried to correct them but they are still way off. But there are just so many variables involved. Any normal driver can beat the EPA numbers, while hypermilers can do much better, and lead-footers are draging the bowels of FE......haha
