Businesses that have many vehicles on the road monitor how those vehicles are being driven. Aggressive driving – including speeding, rapid acceleration and braking – wastes gas. The US Department of Energy (DOE) estimates that aggressive driving can lower gas mileage by 33 percent at highway speeds and by 5 percent on local roads. Observing the speed limit, and using cruise control to maintain a constant speed, also helps with fuel economy. The DOE notes that for every 5 miles per hour individuals drive over 50 m.p.h., they spend on average an additional 24 cents per gallon of gas.
