Are you putting your foot in
Are you putting your foot in it? I can drive my prius at 45 miles per hour and my husband can do the same on the same route, etc. Until you learn to pull back on the gas when the car is at the speed you want, you'll get poor gas mileage. It's a bit of a balancing act - use cruise control when you can and this should help as well. The mpg meter will help you learn to drive efficiently
