Acting as a handy gadget that helps you keep your gas bills low, the PLX Kiwi is just what you need to help you drive better. It keeps a tab your driving capabilities and computes a way that will help you increase your gas mileage. At the risk of being labeled as a backseat driver, the device nags you about your diving so much that your wife's bickering pales in comparison. It tabs your smoothness, drag, acceleration and deceleration and then gives you a full report. Apparently it will give you an average fuel savings of 20%, translated it means anywhere from $500-$1000 per year.

PLX Kiwi will be out later this month for $299, pay me half the amount and I'll give you a reading right away.
