It worked. Changing my driving habits and moderating my acceleration and weight on the gas pedal increased my mileage in the SmartCar by 10.4%. This is all city driving in San Francisco. What if every driver in America could improve their gas mileage by 10% just by changing their acceleration habits. Maybe that would have an impact on oil prices, now, instead of other solutions which might create more oil supply ten years from now or cost $1.3 trillion in new infrastructure to deploy. Too simple, I must be wrong.
