My commute is about 55 mi. each way, mostly highway, mostly no significant traffic. I drive mostly between about 60-65 mph. 55-60 on highway upgrades and sometimes 70ish on a downgrade.
What kind of driving are you guys doing? Are you driving at my kind of speed and distances?

I'm slower than you, and I'm not on the freeway as much. I stick to local roads, where I can rack-up big FE numbers through P&G with the engine off. On the freeway, straight out without hypermiling and at about 50-60 MPH (holding a consistent 16.5 or 16.9 throttle) I get only about 49-52mpg. On the surface roads is where the big gains are. Lately I use a technique on the freeway I call "GLEN" meaning "Glide, Load, engine-on, Neutral." I accelerate at 70-80% load from 50 or 55 to 60 or 65mph (always a 10mph arc) then coast back down to the starting speed in neutral. I get modestly higher freeway MPG this way, maybe as high as near-60 but I don't think so, and I have not reliably quantified it.
Bottom line: I avoid freeways and take my 11 mile commute a little more slowly through EOC. I don't however drive all that slowly on average... just a little slower than traffic.
