Most people are not very receptive to the idea of slowing down from their usual speed and driving a little slower on the highway, freeway or interstate. If you do want to save money bad enough, though, you will be willing to make some sort of change to the speed that you drive on these types of roads. It may be hard at first, particularly when people start passing you on the road, but remember that you are saving yourself a substantial amount of money in the process!
