The best way of cruising down a highway is to maintain a constant 80-100kph (generally the cruising speed that gives best economy). Acceleration uses up fuel, and decelerating just throws away any kinetic energy you use during acceleration. In other words, maintaining a constant speed is good for your pocket!
