They can, in case that road passes through a building as a passage. You need some visual confirmation from the ground to determine that (like Mapillary, Wikimedia Commons or... well, there are few other sources that you can legally use for mapping OSM). You can try browsing using this website: https://nakarte.me/#m=18/41.71032/44.76388&l=O&n2=_wm

reverted - simple following iD's validation issues which are often faulty, like not all branches of Bank of Georgia are called Solo; railway tracks under roof are not tunnels, just covered; and BoG ATMs able to receive coins. Please don't fix issues that you are have no expert knowledge of, iD is not a good guide for that.

"tertiary" or "unclassified", difficult to judge, which one.

Hi! Actually, this roads needs to stay "tertiary", as it's part of the sequence of roads connecting the village of Bevreti to the outer world. See osm.wiki/Georgia#Categorization

It that dog paraplegic and doesn't move at all? If it does move, even be it to the street above and back, it can't be mapped.

P.S. Google Maps are full of shit.

Hi! "public_transport=stop_position" is an additional clarifying object that provides info where precisely the bus stops on the road. By itself, it doesn't mean that the bus has a stop around here; it just doesn't work alone. An object with public_transport=platform is required; even if there is no physical platform on the ground. And also, please restore ref=2482, it's the main tag to designate the number of the bus stop, consumers such as Organic Maps use this tag and not the more sophisticated gtfs:stop_id.

Hi! Actually, in English usually all the words in a name are capitalised, even if they just describe the type of the object. The same convention is established in OSM, so it should be "6th Street 1st Lane".

At least some of these are actually unpaved. It would be interesting to know if these were mapped from the ground or... somehow else.

Thanks for adding info about the graves & memorials. One point: please add name:ru without accent marks (if copying from a Wikipedia article, it may be convenient to select the name from the infobox at the right). Also, https://en.wikipedia.org/wiki/Zacharia_Paliashvili for some reason became Sakaria...

Are you sure that way/62215493 connects to Nugzar Shanava Street?

no idea, actually, which one would be better...

reverted - accroding to cadastre, the whole building is 16 კორპუსი 3, see https://maps.gov.ge/map/portal . However, if there are any photos of house number signs, they would take priority

Hotel, inside a disused cinema?
Also, I was unable to google any info about such a hotel, only about an estate developer with this name. Maybe office=company?
