Right now that's one of my biggest issues, in the 3 lane areas I don't really care if I'm going slower but in the 2 lane I feel like I'm holding traffic up. I often try to keep up with everyone until I encounter a good semi (nice low mud flaps, and not a damn gravel train that throws rocks and crap) and stay 75-100ft behind them for as long as I can. I'm amazed how much better mileage I get if I stay in someone's path of turbulence, beyond 100ft it seems to dwindle.

I actually have instantaneous mileage on the dash already, it's on the same page that says how many cylinders I'm using. When going 45-55mph I can stay in 4 a decent portion of the time... any faster than that and it only flickers into 4 while I'm coasting.

Does pulse & glide really make sense on an auto transmission? Also I was reading somewhere that people claim taking off briskly saves fuel, I can't imagine it. I'm sure the dash would read higher, but hand calculating...??
