Proposal talk:Change the meaning of the UK highway trunk and primary tags
As a sometime road geek, I vote no. The consensus works. I've encountered similar wholesale changes before, when it was just dealing with an attempt to reclassify all the roads in central Leeds (see ), so the prospect of having anything to do with reformatting all of the UK's roads on a whim is an absolute non-starter. However if you want to mark certain roads as "properly" trunk by the UK definition by all means use, if in England, the operator=Highways England (they've recently rebranded) and highways_england:* tags.

- "There has long been consensus on the tagging, and there is an equally long history of new people turning up and wanting to change it to match the official trunk classification." 
- Can you please annotate your comments like everyone else does? There is not a long history: from time-to-time people with little knowledge of OSM, but a great deal of enthusiasm for road geekery appear demanding that we change something which has just worked fine for nigh on 15 years. The consensus is exemplified not by vociferousness on mailing lists, nor by undiscussed edits, but by the vast majority of mappers finding nothing wrong with the existing approach. To date this is probably in the tens of thousands of contributors compared with perhaps less than 10 advocates of alternative approaches. In addition there are a multitude of apps based on OSM which consume this data which is then used by considerably more people than those who contribute. I can confidently say in these pool of perhaps several million people the number who think things would be improved by adopting a system which you yourself have shown is inconsistent across the UK for some undefined benefit is approximately 1. The bar for change is very high and requires a really persuasive arguement with concrete examples of significant use-cases which the current scheme makes impossible. You are wasting a lot of people's time. Please stop. SK53 (talk) 19:55, 16 September 2021 (UTC)
"more closely align with global OSM terminology" - you mean, apart from Spain, New Zealand, the Baltics, Scandinavia, and so on, all of which have single-carriageway highway=trunk with low-speed urban sections just like the UK does.
You have 86 (eighty-six) edits in OSM and have steamed in trying to change a well-understood, simple one-to-one mapping, established for over 10 years and reflected in easily-observable road signs, with a complex process that requires consulting an external, non-public-facing dataset and would significantly break a lot of downstream uses. Please just stop.
You can't use a global wiki vote to gain authority to retag the highway network of one particular country, over and above the wishes of that country's mappers. OSM doesn't work like that. And note that the proposal process page explicitly says "never use a vote result as a permission for large-scale re-tagging of existing objects".
Why don't you start by formulating network=* or designation=*? highway=* itself doesn't necessarily show this either. I see a few already have operator=*, and highways_england:area=* as recorded in Roads_in_the_United_Kingdom#Additional_Highway_Tags_for_the_United_Kingdom. ---- Kovposch (talk) 19:57, 16 September 2021 (UTC)
OSM definitions are based on UK status quo
I don't think you understood Tom Hughes' point about definitions. OpenStreetMap started in Britain and roads were among the first things mapped: see Map Features wiki from 2006 and this thumbnail
