Libya's terrain is quite unique, with almost all of its territory covered by the desert. Majority of its major cities are located along the coast of the Mediterranean Sea. This terrain dictates that Libya's main roads travel along the coastline.

With the guidance of GPS, they didn't have to worry about getting lost even when off the main roads.
