Usually cars are just machines. You can push them as hard as you want…until now. Nissan’s new ECO Pedal pushes back. The system is designed to provide maximum fuel economy by monitoring current conditions and suggesting more fuel-efficient driving. The car decides the necessary acceleration, and if it detects too much pressure on the accelerator pedal, it will provide counter pressure in an I-don’t-think-so-Dave manner.

Nissan claims a five to ten percent improvement in fuel economy when the ECO Pedal is utilized. It wants to start using the system next year, and unlike HAL, the driver can shut off the ECO Pedal at any time.
