I have had an Automatic car adapter for well over a year. It plugs in to the OBDII port in your car. It will tell you your gas mileage, driving distance, where you parked, hard brakes, fast accelerations, going over 70 mph. It gamifies your driving. It can also hook up to If This Than That workflow to do things like log all of your business trips into a spread sheet or notify someone when you arrive a specific location. So far this week my score is 100. I have gone 85.5 miles with a MPG of 25.6 on my Chrysler Sebring. It is nice because you can have one on your newly licensed teenage driver and talk to them about their driving. They just started to send an email letting you know how you did the previous month.
