WILL AUTOMATED CARS save fuel? “Drivers cause all sorts of problems. They hit the brakes too much and accelerate too quickly. That can waste a third of the gas on a typical drive. Bad driving also creates traffic jams. In the U.S., drivers waste two billion gallons of fuel each year while stuck in traffic, according to a study by the Texas Transportation Institute. Just think of the gas burned in that 2010 Chinese traffic jam that lasted almost two weeks.”
