I live roughly 1.5 miles from work, and during that short drive I have to stop at 6 stop signs. So the engine is cold, and there is only one stretch of .5 miles or less where I can coast. I do ok on longer drives, but the drive to work is dragging down my average mpg something fierce. Accelerating from all those stops is particularly fuel draining. There is an alternate route I could take that would make it more like 2 miles, but still has 5 stop signs. I'm not sure what I can do to squeeze more mpg out of this commute.. I've actually taken to driving my 2nd vehicle to work so I don't "ruin" the average on my new car, but that's kind of silly. I bought the new car to drive it.. The vehicle is a 2012 Mazda 3 Automatic with Skyactiv.
