Other mapping softwares include rest area/exit area information as you drive down a highway.

The information appears on the map and shows where the next exit is, and briefly shows what services are available there.

It’s helpful on longer trips where you may want to be maximizing your time on the highway. (For example, I may know that I have 50 miles left on a tank of fuel, but it’s not always clear if I need to stop immediately for fuel, or if there’s another service station 25 miles down the highway)
