Not sure I understand what you mean with that.
They are the best tags if, as I said, only motor vehicles are allowed. Of course, it depends on the exact intention, but with > bicycle <https://wiki.openstreetmap.org/wiki/Key:bicycle?uselang=en> no > foot <https://wiki.openstreetmap.org/wiki/Key:foot?uselang=en> no > mofa <https://wiki.openstreetmap.org/wiki/Key:mofa?uselang=en> no > moped <https://wiki.openstreetmap.org/wiki/Key:moped?uselang=en> no > as strange as it may seem, one allows horses, ski, ice_skates, and inland_skates, and that doesn't seem to be the intention. And it may well be that carriage=no is necessary too. With access=no motor_vehicle=yes, one disallows all that but I shouldn't have written so fast: mofa=no and moped=no must be kept because they are exceptions to motor_vehicle=yes. In fact, the poor idea is to try to solve each and every particular case by giving its tags. The best answer to such a question is "how it works". Starting with access=yes, in the land-based <https://wiki.openstreetmap.org/wiki/Key:access#Land-based_transportation>, water-based <https://wiki.openstreetmap.org/wiki/Key:access#Water-based_transportation> or rail-based <https://wiki.openstreetmap.org/wiki/Key:access#Rail-based_transportation> transportation tables, * all category (indentation) levels directly below a category=yes, inherit the *=yes status o if one of these subcategory=yes is wrong, the subcategory=no tag must be added o all category (indentation) levels below such a <subcategory>=no, inherit the *=no status + if one of these sub_subcategory=no is wrong, the sub_subcategory=yes tag must be added + etc. all that recursively. One ends up with a complete yes/no table. It depends on the intention and it's very simple. Cheers André.
