I believe you’d want to avoid the main roads or drive off road as much as possible.
That makes sense. Unless you are in the dessert or maybe the steppes, there probably are still choke points where you have to drive. Still, staying off the roads sure sounds right.
My Father was in the combat engineers in WWII and according to their history, they once dug 18 mines out of a 6 yard square piece of ground. I guess the Germans considered it a good location for a mine.
