An automaker rolls out a new gas pedal that is designed to save fuel. Nissan says it will soon begin selling cars with gas pedals that push back when a driver tries to accelerate too quickly.

It says its Eco Pedal system can help drivers improve their vehicle's gas efficiency by five to 10 percent. Drivers can disable the feature when necessary.

The gas-saving pedals will be available in Nissan vehicles next year.
