If you are one of the many people who drive at over 70 miles per hour frequently, you are costing yourself quite a bit of money! Your fuel consumption will be up to 25% more than if you were going 55 miles per hour, depending on your vehicle and other driving conditions. With gas prices surpassing four dollars per gallon in many places, it is easy to see that this kind of cost can add up, especially if you are driving a vehicle that is not exactly fuel efficient, such as a van, truck or sport utility vehicle.
