Showing lay-bys

Are parking lay-bys shown in OSM and if so how? That is to say places off to the side of a road where vehicles can stop for a short time without interrupting other traffic.

The few layby I did in form of a node with amenity=parking + parking=layby show up with a P in Carto standard. TagInfo says there’s over 10K use of the tag displaying them too when mapped as area.

Thank you.
