There are several thing here that gives clues.
A trend in modern housing estates is private shared driveways/parking areas. Generally this is what I am seeing based on experience of seeing these on the ground.
The big indicators I can see on imagery is that the kerbs are crossed, indicating that this is not a public adopted highway.
This is new build, it has not existed long enough for infill, if this was intended to be public highway then turning areas at the end of Rowan Road and Drover's Close would not have been provided. Close in a name indicated that it is not a through road.
As for a driveway being a way to access another roadway, then this isn't. It should only be used if you have business at those properties, in that case there is a choice of entry/exit. If you need to travel from Rowan Road to Drover's Close then you should do so via Goldworkings Crescent.
The other thing to take into account is OSM history, this area was mapped by local mappers by survey and we tend to ignore private driveways as they have little interest to the majority of map users. Had this been a residential road I am pretty sure they would have mapped it, again its newbuild so would have been built at the same time as Drover's Close and Rowan Road.
For now at least, I would err on the side of caution and map this as private. By all means add a note to prompt a local mapper to go and have a look what it really is. In fact the Optimus Way link is due another survey so will have a look in the next few weeks if someone hasn't beaten me to it.
BTW I was the first mapper to map this estate, Birch Lane from Kirby Road.
Hope this helps Phil

Hi, welcome to OSM. Thank you for your edit, however should the name not be F.H Brundle?
Cheers Phil

This tunnel is at ground level, I have been there and I am the mapper who surveyed and mapped it.
It is a connection of the old road, probably the actual course of the roman Watling Street. The reality is that the road and the cycleway are on an embankment.

Hi, welcome to OSM. This edit seems to have gone a bit wrong. You have added your business on a verge, there are no building here. I am going to revert this, but as long as it is verifiable then please add it again in the correct location.
Cheers Phil

We do not map to make things uniform. We map what we see on the ground.
The wiki should not be taken literally although in this case "On the other hand, the link ends at the latest where it joins a different road" does apply.
There is also mapillary to give a clear view, the green portion tells the Trunk, or link to trunk.See https://www.mapillary.com/app/?focus=photo&lat=51.64044820708375&lng=-1.843661125751055&z=17&pKey=E9y_-FPy5lr8jJi60tMtPA
These ways have the
ref A419, again indicating not secondary.
Please revert this change.
Cheers Phil

Why?

Hi, please could you explain the reason you have added layer=-1 to this tunnel?
What information do you have suggesting that it is below ground level?
Cheers Phil

Hi, are you sure that this is a publicly accessible residential road. Imagery (kerbs crossed and colour) suggests that this is a private shared driveway. The name Drover's Close is another indicator that should be taken into account.
Cheers Phil

I have reverted this changeset

Thank you Peter

Maps.me is a bit limited in what it offers, however in OSM if a category hasn't been mapped before you can choose your own tags in editors such as iD.
Maybe use tourism=gallery, or invent a new tag such as amenity=cultural_centre. Possibly map it as an area, and then include things like the restaurant and galleries as nodes within the area.
I assume it occupies the space where GAP was? If so that needs to be removed.
Cheers Phil

Hi welcome to OSM. The website seems to imply that this is some sort of shop however you have mapped it as a museum.
Please could you explain what it is?
Cheers Phil

Hi Peter
The consensus among mappers is that references that are not verifiable on the ground should be put into other tags.
In the case of rights of way we use the prow_ref tag, please could you use this instead.
More specialised renderers do display them, see https://map.atownsend.org.uk/maps/map/map.html
If you want to see an example see way/355132221
Cheers Phil

Hi
I am assuming you are trying to tag the Trains to signs?
This is not a name and the name tag should only be used to tag actual names, not as a place to add random information.
Maybe as use a different tag such as direction=Liverpool?
Cheers Phil

Hi, this edit has broken the tagging of this object. The Llangollen railway is preserved and it is incorrect to tag it as a normal railway just to make it appear differently on one particular renderer.
This is what is called 'tagging for the render' which is an absolute no no in OSM.
Please remember that OSM is a geographical database, which can be rendered in many ways.
Cheers Phil

Hi, I have been here and there are definitely no signs. If I have missied something then please point me to some photographic evidence.
In OSM we map what is visible and verifiable on the ground and I am convinced that this does not pass that test.
Cheers Phil

Hi Jon, thank you for removing that.
To answer your questions firstly the forum gets very little attention in the UK, we are far more active on the talk-gb mailing list https://lists.openstreetmap.org/listinfo/talk-gb.
OSM is a geographical database that can be rendered in many ways. The cycling layer is just a specialized render of OSM data, emphasising those features of interest to cyclists.
OSM data is mostly created by the public, we import very little in the UK and that is mostly boundaries.
The GPS tracks may have comments stating what they are, we essentially upload gpx files. Most of mine are from my gps, occasionally they maybe from OSMand, but that will be car and road stuff.
Routes in OSM are done as relations, a collection of ways, but these should be verifiable i.e. signed on the ground.
For creating my own routes I use graphhopper.com, which allows via points and different modes.

Please do not abuse the name tag, this is Wales and the local language should take priority. If you want to make a map of English names then you can using the name:en,

Hi, not sure if you have been here, and I am assuming that this is an armchair edit, but this is very clearly not a peak as it is on the side of a hill.
Please only map things that actually exist.
