> t also has this eco game thing, where you earn “points” when you drive efficiently, and it penalizes you for driving inefficiently (hard acceleration, braking instead of coasting, inconsistent speed). This “game” has transformed the way I drive, it should be in every car. If it also earns a driver "points" for not impeding other traffic while driving efficiently, and penalizes a driver for blocking other vehicles that want to pass, when the driver could safely move to a space in a non-passing lane, then it might be welcomed by many drivers. IMHO, the main reason that Prius drivers have a reputation for driving selfishly while hypermiling is that Toyota put the current MPG in big numbers on the default display screen, and many Prius drivers got into the habit of optimising their driving for a lager MPG number, to the exclusion of being aware of other traffic on the road.
