@Mateusz

I just got alerted that you added a paragraph on the wiki Page
OSM_tags_for_routing/Access-Restrictions
<https://wiki.openstreetmap.org/wiki/OSM_tags_for_routing/Access-Restrictions)>
in which you state:

" Note that explicit tagging of access repeating what following tables
imply may be still useful. For example bare highway
<https://wiki.openstreetmap.org/wiki/Key:highway>=path
<https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath> may mean either
"surveyed and all defaults apply" or "mapped from LIDAR, not surveyed, may
be private". In contrast highway
<https://wiki.openstreetmap.org/wiki/Key:highway>=path
<https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath> + foot
<https://wiki.openstreetmap.org/wiki/Key:foot>=yes
<https://wiki.openstreetmap.org/wiki/Tag:foot%3Dyes> + bicycle
<https://wiki.openstreetmap.org/wiki/Key:bicycle>=yes
<https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Dyes> is more clear what
is its meaning."

I do not agree with that statement. If highway
<https://wiki.openstreetmap.org/wiki/Key:highway>=path
<https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpath> has the default
implied access values foot <https://wiki.openstreetmap.org/wiki/Key:foot>=
yes <https://wiki.openstreetmap.org/wiki/Tag:foot%3Dyes> + bicycle
<https://wiki.openstreetmap.org/wiki/Key:bicycle>=yes
<https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Dyes> (and horse=yes)
then that means that an armchair mapper should add access=unknown to the
tagging.

BTW foot <https://wiki.openstreetmap.org/wiki/Key:foot>=yes
<https://wiki.openstreetmap.org/wiki/Tag:foot%3Dyes> + bicycle
<https://wiki.openstreetmap.org/wiki/Key:bicycle>=yes
<https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Dyes> and horse=yes may
also be interpreted as "iD mapper has ticked all fields"
