nah ... There is a reason why these ways are mapped. They are visible clearly on DGM-Schummerung of NRW-Atlas. On aerial imagery they are also visible, although not that clearly. It depends on the time of the year (season). I know that from my hometown. When the grass is high you cannot really distinct between the way and farmland. But when the grass is cut you see traces of people walking with dogs.
