I thought that it might be helpful if we post all of those little ways that those of us who know how to drive to get the best mileage can share with those who don't. You don't have to be a Prius owner, per se. But I'm thinking that perhaps there are lurkers out there who drive a conventional car who just can't seem to get good mileage. Or, perhaps there's someone who got a Prius and can't seem to get that mpg up to where the rest of us find it effortless to attain. If you're one of those people, here's the help that you need. I'll start it out with one and all the other mileage gurus can contribute. My favorite analogy to use is that of a bicycle rider. If you've ever been out on the road and huffed and puffed your way up a hill only to be passed by someone else on a bike who just glides past you without seeming to be even breathing hard, you can appreciate how hard your car works on that same hill. If you can learn to ride a bike efficiently, you'll realize what you need to do to drive your car efficiently. I see a lot of people braking their way down a hill and at the bottom, they have to accelerate up the next hill. That's a needless waste of gasoline. In a conventional car, as you coast down the first hill, the car's speed gets faster and faster. With a Prius, the car channels the energy of that momentum back in to the car's power system so you never speed up much. In either case, you develop a sense of how to begin at the top of a hill slowly enough so that when you're going down the hill, you don't go too fast. Just as importantly, that sense also tellls you when to accelerate slightly so that when you start going uphill, the car is going fast enough to reach the top without your having to give it more gas. The moment of slight acceleration, for me, is usually towards the end of the descent. The trick is to know how much gas the car needs for the upward trip and give it that much before hitting the bottom of descent. Practice this a lot and it will be second nature to you. Not to mention that your mileage will go up, no matter which kind of car you drive. It's something that you just develop a sense for, not something that you have to think about much. As the cyclist's saying goes: "Love the hills because it doesn't do any good to hate 'em."
