I commute to work in heavy traffic, about 30 miles each way and I got few runs at 46mpg and normally average 41-43 mpg, without even trying. Of course because of traffic I can't drive too fast and if I didn't keep up with everybody else they would run me over without even looking, besides the fact that i do need to get to work on time, so I can see that you can squeeze 50mpg out of the car during pleasure drive in the country, probably more with some practice.
