(late resume)

You (all) may or may not notice that I often subconsciously choose the wrong words to represent ideas that I am very sure to be correct. This is one of them. To strengthen/clarify my point, I can agree e.g. if cars turn into Yan Ching Street and then use Tak Chung Court to u-turn, or just directly u-turn at the Tak Chung Court junction, then it is perfectly reasonable and acceptable; but I was trying to describe the u-turn right at the Y-junction at Yan Ching Street.

As @Kovoschiz can appropriately describe better than myself, that Y-shape "belongs" to the junction, so that's not the usual kind of place where we require valid irl sources to tag features.

Still, from this note and long discussion, I can detect 2 issues that are very good candidates for Discord deeper discussion/clarification. Which means this note should be kept open for longer until we sort this out.
