A map on paper and a route on a screen answer different questions. Turn-by-turn handles one choice at a time. The next turn. Paper covers the shape of the whole thing. Everything not on the line. This distinction is the whole of it. Following directions teaches nothing. You arrive without having learned the layout. Which matters very little for a single journey and considerably across a week. The overview also shows the alternatives. Both appear on paper. An instruction gives one answer and conceals the rest. Which is efficient and occasionally wrong for your purposes. Scale decides what a map contains. Broad coverage, little detail. Depth against breadth. Choosing the right one for the purpose is most of the skill. The lines carry the information. The map shows it and nobody looks. A single session. The physical format holds up. It needs no power and loses no signal. It can be marked. Which turns it into a record afterwards. Its weaknesses are equally real. Physical limits. Wear is real. The combination. Each doing its job. The people who understand contentment the places they move through generally looked at the whole route before setting off.
