There's a road near here (Hampden Road) with the usual Evel Knievel sign at its start (it's a cul-de-sac). The sign is qualified with the equally usual "Except for Access".
It is shewn in OSM as access=destination; bicycle=yes; highway=residential
Where does access=destination come from ? Is it a made-up value ? (Not that there's anything wrong in that)
Thing is, access=private, access=permissive and so forth, refer to all classes of traffic whereas, here, it seems to refer just to motor traffic. Which is correct
I would have put the "destination" bit as motorcar=destination | motorcycle=destination and left everything else as defaults (access=public being assumed)
