My commute consists of driving ~23 miles along the Garden State Parkway during the beginnings of rush hour each way. Some days I'm averaging 60, some days I'm crawling at 7. That's the Jersey crap shoot.
I'm going through that list and there's a few things I'm doing already like driving slower (doing 75 got me to work faster but...) and reducing idling (as much as I can on available routes). I love #17. As a triathlete in training I avoid fast food like the plague, let alone go to the drive-through!
