People who are often on the road are less likely to be updated with what's going on. Aside from the fact there is no TV in the car, they can't always rely on their radio for news or updates. While they will always have their cellphones with them, it's not really safe to use it while driving. But it's important for them to know what's going on, just in case there's a sudden change in weather or a certain if there's a road that they can't pass through. Just so they can change their course immediately and avoid the hassle.
