Cycleway bridge https://www.openstreetmap.org/?mlat=50.03088&mlon=19.81907#map=19/50.03088/19.81907 is quite wide, still it is clearly a cycleway. Some areas with heavy tourism and slowly recovering nature may have extremely wide paths, Czerwone Wierchy in Tatra Mountains are one of sad cases. https://commons.wikimedia.org/wiki/File:Czerwone_Wierchy_widok_w_stron%C4%99_Tatr_Wysokich.jpg It is certainly path (tagged as highway=path or highway=footway) > General comment: I am happy to map/tag in any internally consistent way > according to community consensus.

For simplicity and to avoid discussions people try to assign them some administrative matches (maybe it works in UK as OSM copied UK administrative classification), people try to assign physical classification. There are unpaved highway=trunk, there are paved highway=track and so on. > A way that is used to access a private residence from a public road is > highway=service, service=driveway (functional classification), unless it is > too long (exact distance not specified), or too rough (physical > classification). > Way used solely to access a private residence is always highway=service, service=driveway no matter whatever it is short, long, paved, unpaved, lit, unlit, ugly or 22 lanes wide. Why you think that "too rough" driveway is no longer highway=service, service=driveway? (if based on poor wiki docs then I would be happy to fix, if it is based on iD presets then I would not recommend using iD presets to learn how OSM tagging works - there are some problematic cases like peculiar description of highway=track that are deliberately unfixed) > If this is confusing for an experienced mapper and geodata geek, how are data > users/consumers supposed to figure this out? > Use OSM Wiki, use taginfo, look at data - if confused ask on mailing list (or elsewhere).
