Much like driving in real life, it pays to be aware of your surroundings in the game. Some of the highway exits (particularly in Arizona) are a bit confusing so be sure to check your map for your turns in advance. Also beware for things on the road like sudden traffic, accidents, road work, and road closures. All of these random events can impact your journey as well. Don't worry about tumbleweeds, though. Unlike real life, you can run over them without messing up your tires!
