Ask for permission first from the original uploader. If permission is granted, then it’s a greenlight.
I added some bus route, yes, by taking an actual ride. E.g. there’s one (incomplete) route in Seberang Perai and another (KLIA-KTM Nilai) - but then again, the latest route may subject to change. Incomplete route is better than nothing at all. Well, ground truth may take some time, but anything is possible if you are patient enough. Feel extreme enough? You might want to tailgate a bus route from the comfort of your private vehicle.
