* I reverted the changeset but fixed the Tsuen Wan Line layering issue.

I'm reverting this changeset because only layers -5 to 5 are used, and other layer tags are unlikely to be supported by software. (layer=*)

It might be appropriate to ask on the tagging mailing list, since I personally haven't actually tagged a lot of links recently.

However, my interpretation is that because those three ways don't have to be used to drive onto the motorway (they have to be used in driving from Tsun King Road or Tai Po Road – Ma Liu Shui to Sha Tin Racecourse), they shouldn't be tagged as motorway links. The service road also doesn't exclusively provide access to the destinations, because the interchange is incomplete and it is necessary to drive through Sha Tin Racecourse in driving from Tsun King Road to Tolo Highway. (To my knowledge, the "service" roads inside the racecourse are public roads for routing purposes. I don't know whether the interchange is on public or private land.)

An additional distinction is that in Hong Kong some (but not all) parts of motorway links are themselves legally classified as part of controlled-access highways, and road signs indicate such. What you have effectively been doing in a lot of your recent changesets, including this one, is removing this distinction where it exists. I don't know whether this is correct, since some other countries might not have those explicit delineations shown by road signs.

I don't think this is correct. It's possible to drive from Tai Po Road to the service road inside Sha Tin Racecourse, so the slip road which allows said journey doesn't directly function as a motorway link. "If a road leads from a motorway to a non-motorway, only the portion that solely carries traffic to or from the motorway should be tagged as motorway_link." (highway=motorway_link)

I unfortunately have to revert your edits since access=no shouldn't be used on roads which are accessible by the general public. The correct tag is either no tag or access=yes (plus more specific restrictions).

There is a lot of software that depends on these assumptions, so the interpretation shouldn't change barring extraordinary circumstances.

You don't have to fill out all of the buttons in the iD editor interface, and the interpretation is not defined by the editor. If a road does not have any access tags it is assumed to be a public road, and if a road does not have a oneway tag then it is assumed to be a two-way road.

• Please edit name tags properly (e.g. clear errors for node/4398872742 and way/669121631). alt_name shouldn't be the same as name.
• You should probably use JOSM instead of iD, particularly since I've noticed you tend to create a lot of label and alignment issues when using iD (which everyone else has to clean up; e.g. changeset/67105708). It's also more suited to high-volume and precise editing, and the object validation (which iD doesn't have) is also quite useful

I'm reverting this changeset separately because the node was previously in alignment with the other nodes of the motorway link.

This changeset is not problematic.

Additional issue: Since the road is at-grade and the bridge has the appropriate layer tag, layer=-1 is not necessary here.
