This was from a single trip from a gas station in Bay Ridge Brooklyn to Elmont L.I.. This is practically my daily commute, of course with much more local mixed in than this trip. A bit of psychological manipulation and throttle control can go a long way. Though I must say, I did go relatively slow on the highway (50-55mph) and was in closed loop mode for as long as possible while approaching redlights.
Take a glance at my sig with datalog from Fuelly and Ecomodder. Don't get me wrong, every now and then I mash the pedal in frustration when someone cuts me off or whatever it may be in NYC, granted it's slow as a snail. I usually average 55-60mph on the Belt, SS, LIE, GCP, BQE, etc. I don't block the road (be it local or highway) either like your typical "grandpa" on the left lane.
