Minimum road/road widths

Evening together, with me in the area there is a road that leads past an industrial area. Is inside, but there is nevertheless tempo 70 allowed. In any case, the lanes (or lanes?) are separated for each direction by a thick, white crossed line. So there is exactly one lane in each direction. However, for each lane the lane is about 5 meters wide, so there could easily drive 2 cars side by side. Is this at all permissible and allowed? If you follow the road marking, there is only one lane in each direction. But if you drive “middle” on its lane, often enough come from behind which push you away and overtake them. Would be allowed to overtake there? Incidentally, there is an absolute stop ban everywhere, so parking vehicles don’t bother there either. Have a picture attached. What do you think when planning such a road?
