I did some off road travelling in Croatia about 15 years ago, thanks GPS driving us into some farming roads.

Only when I got out of it, I realised how stupid idea that was to keep following the GPS, on some country side villages the markings of the war were still visible, with abandoned buildings full of bullet holes.

Naturally having mines still around was a possibility that I completly forgot about.

Bullet hole areas != land mine areas.

Think of it this way: bullet holes are where the fighting took place, while front lines have fluctuated. You don't want to mine an area that your soldiers might want to advance through. Land mines are placed when front lines have stabilised (like they are right now in Ukraine) to prevent the other side from advancing through. You only do that once your side has no intention of advancing further.

As such, land mines were usually properly documented and clearly marked as such after the war with giant skulls and red tapes, usually with some combo of words "PAZI MINE" ("beware, mines"). So while there are still rural areas that are littered with bullet holes, that does not mean those same areas were full of mines. It's also highly unlikely for a mine to be on any road, especially if it looks fairly well-maintained. You can take a road going through the minefield just fine, but you should never be one of those urban explorers that intentionally strays off of the road to look at the ruins on the side of that road.
