That would be interesting to see.
Maybe the map would reveal he's going in circles etc. lol
A bit of a problem is the truck driving scene, where the background isn't so visible so we don't see if it's turning.
Well there's a youtube (I Think) documentary I saw showing how they made the film. It was a large plot of land but yeah, more like zig zag and circles with clever camera angles and shows you how they did the illusion of "no cuts". Worth watching. Not sure which is more entertaining (I haven't watched 1917 yet). They did dig quite a bit of trenches and all, but obviously it's a movie illusion like always.
