I'm in the middle, getting around 44mpg. 5MT. Most of my drives are ~5 miles, in the city. Gentle acceleration, coasting to red lights when possible, but always more or less keeping up with (reasonable) traffic. Haven't dealt with winter yet to see its effects, though I've got my engine block heater installed and am excited to see how it helps. Whenever possible, I do get CostCo gas, since it's cheaper and supposedly "better". It may or may not be an excuse to go get a churro though.
Even when I essentially idled for 2 hours while the entire freeway had to merge and exit due to a car accident, I still got 42mpg that tank.
If I had to guess, I would say "racing off every traffic light" would be the biggest culprit for low mileage. I'll say this though, my wife drives like me, about the same route, and only gets 26mpg in her 2010 Hyundai Accent (automatic). So low 30's for pedal mashers is still pretty awesome, comparatively.
