Slow down, people!

Lead-footed drivers looking to take the pedal off the metal can look to the Nissan Motor Co. to help curb their speedy habits.

The Japanese auto manufacturer announced last week that all new cars will soon come equipped with a gauge that registers real-time and average fuel efficiencies, allowing drivers to know how their driving methods affect fuel economy. Upon acceleration, drivers will instantly see spikes in fuel consumption on the instrument panel device.

During Nissan’s trials, the gauge helped prompt drivers to accelerate and brake more smoothly, which resulted in a 10 percent fuel savings, on average. According to the carmaker, the device is part of an effort to curb CO2 emissions and promote environmental technologies.
