Unless you get a Drivemaster Pro. This little device promotes more efficient driving by analyzing several factors and computing how "Eco" the vehicle is being driven. A display appears to give the driver immediate feedback, with a dial that spans from red to green. The manufacturer's website is in Japanese, so details are a bit fuzzy. It is clear, however, that it uses a series of sensors to examine different aspects of vehicle operation in order to calculate how well the operator is driving.
A company brochure (PDF) discusses HINO's commitment to increasing the efficiency of trucks and busses. So, though discussion has talked about putting this into everyone's car, it looks like it is really meant for use on commercial trucks. As HINO points out, a heavy-duty truck will use about 330,000 liters (nearly 88,000 gallons) of diesel fuel in its lifetime, so improving efficiency of these vehicles has a much more significant impact than improving the efficiency of a passenger car.
A device like this isn't going to turn anyone into a hypermiler all by itself. But it will help drivers keep their vehicles in their operating peak range. These meters are already popping up in hybrid cars, and Toyota will soon be including a primitive version of this device in every car they sell in Japan.
