If you have a naturally heavy gas foot pressing against the pedal no matter what car you drive, chances are you’ve filled up your tank much more often than normal, law-abiding citizens do. The PLX Kiwi is here to help you save gas in this time of ever rising costs by displaying your current fuel consumption as you drive. In addition, there is a scorecard that lets you know whether you’re a responsible driver or not without putting the pedal to the metal unnecessarily. Priced at £299, I’m not too sure whether it will be worth it as constantly checking yourself and using some common sense will go a long way in helping you save on your mileage.
