Please see previous comments. The segregated path here is mapped, it needs to be amended.

Hi, Looks like a segregated cycleway both sides, no cycle lanes.
Regards Bernard

I forgot to mention guidance for cycle ways is here :-highway=cycleway

Hi, Welcome to OpenStreetMap.
It does not look like this two-way highway has a cycleway=lane to either side, please see here for advice on cycle lanes :-cycleway=*

It looks like this section of Billet Road has a segregated cycle-way to the south side only. This being mainly separated from the highway proper by a grass strip, thus it could be mapped as a segregated cycleway on its own.

Hello Philip, Not at the moment, the tags that are sometimes rendered are listed here :-leisure=track
You can of course make your own tag, maybe sport=remote control car but it wouldn't get rendered being a seldom used. Better to add the track name or the name of any club that operates from there, it would help other folk and it would be rendered.
Regards Bernard

Hi it might be better to gather all the GlaxoSmithKline buildings into a relation. Thus no need to alter the landuse=industrial area.
Regards Bernard

Hi, this leisure=track could have a tag to describe its use, cycling, running, racetrack.
Regards Bernard.

Hello and welcome to OpenStreetMap.
I would tend to agree with the tag leisure=playground but this one is for older folk only. In order for folk to better use the feature for navigation purposes I've remove the playground tag and added shop=bookmaker.

Hello, regarding these sections of named railway lines that you have now individually named. All are parts of (I think three) route relations, the route relations hold the name of each railway route. Thus there is no need to name each section individually, it only bloats the database without adding any extra information.

You can see the three relations from any link to a section like here :-way/8124466 . Click on a relation link to see it entirely, like here :-relation/6375681#map=10/51.7075/0.2609

Hello, Welcome to OpenStreetMap.
I think emergency vehicles are allowed to and from West Road from King Avenue. So perhaps emergency=yes should be added.

Hi, there is no tag osm.wiki/Tag:'state='. There is a tag osm.wiki/Tag:'addr:state=' however this refers to USA, it is ignored as far as the UK is concerned.
I've therefore removed your state=Northamptonshire tag.
Regards Bernard.

No response so POI removed.

I don't think a back yard in Hendon could be classed as wilderness or a place that would attract tourists. But I may be wrong, could you show how this feature is verifiable to other folk?

OSM data should, as far as is reasonably possible, be verifiable. The principle applies to tags and other aspects of data representation, and essentially means another mapper should be able to come to the same place and collect the same data ("verify" the data you have entered). This principle excludes hypothetical or opinionated data like ratings.

I'll remove the feature in due course if there's no response.

Welcome to OpenStreetMap.
Not really a circle so IMHO better to map the sections of hedge separately thus giving a more accurate idea of whats on the ground.
A house address is not really appropriate for a spot in the middle of and joined to the highway.
postal_code=? is better suited for a highway tag.
Lastly, is it really a tourist attraction? I can't find any reference to it in any arboreal literature.
If you need help marking the hedges please just ask. Regards Bernard

Hi, what actually is the attraction at Node: 5657364521 and how does it relate to tourism please?
Regards Bernard

Hi and Welcome to OpenStreetMap.
A cycle-way sign 100 metre's away would not usually indicate this footpath being a cycle-way. A cycle-way is usually signed where it leaves/meets the highway so one would expect some sign at the other end of Mawson Close.
Regards Bernard.

Amended

Hi, no response so I've removed the duplication and tagged that section as foot=yes.

Hello and Welcome to OpenStreetMap.
Regarding Way: 364613398 I think you've got the elevation wrong (ele=0). The elevation should be measured in metres above sea level (please see :- ele=* ). You must be above 0 here, probably between 5 and 10 metres.
Regards Bernard.
