Ford and Honda are turning fuel-efficiency into a video game by adding more dashboard feedback on hypermiling techniques.

I was going to comment, but the last lines of the article sum it up for me:

“If you make it too much like a game, you’ll have people concentrating on the game and not on the road,” he says. “If you’re driving and thinking only about the environment, you’re going to smack into a tree.”

I’m all for constructive feedback presentation and I like the subtlety of Honda’s changing background color, but I already feel particularly distracted with my XM radio / GPS and it’s 900 features, especially with Florida’s insane drivers who love to signal after they start turning. God forbid they start looking at their fuel economy while blindly switching lanes.
