As if "shift lights" weren't annoying enough... Nissan's new "ECO pedal" has been engineered to encourage good fuel economy with a servo-actuated gas pedal that will push back on the driver's lead foot when on-board computers detect wasteful acceleration. According to Nissan, vehicles equipped with the ECO pedal, and real-time fuel consumption gauges in the instrument panel, have returned a 5-10 percent increase in fuel efficiency. The Japanese automaker says it has plans to begin installing the ECO pedal in models next year, although there is no word on what models, or markets, will get the system. We're betting it's an option unlikely to show up on the GT-R anytime in the near future.
