My hometown is a small one, so I have to remember which (bigger) cities are prior to mine. Also it's not just going on a single highway to reach my destination it's a combination of 2 different highways and several motorways and even roads that lead through villages. There are also often detours because of construction and whatnot.
Maybe important to note, this is Europe. Going from one's country big city to other's country small city. It's not just straight single highway.
