Imagine you've left home and you're up in the arctic on a dog sled. Your dog team is pulling straight and true. You can cover a lot of ground quickly. Now imagine what would happen if one or two of the dogs wanted to go their own way and were pulling off to the side. That would slow you down. You would have to work harder to keep the sled going where you want it. The dogs are all working as hard as before, but you're covering less ground for the same effort. You're wasting kibble. The same is true of your vehicle when the wheels are out of alignment. That wheel that's pulling to the side is dragging down the rest of the car; so you push a little harder on the gas pedal to keep up your speed. You're wasting gas. So have your wheel alignment checked at least once a year. It is critical to get it checked right away if you feel the car pulling to one side. Sometimes we bump a curb or hit a pothole and knock our wheels out of alignment. An accident can take the wheels out of alignment as well. Drivers need to make sure they're tracking straight. You'll get better fuel economy and your tires'll last longer. Now, mush!
