Ah, that's fair; I was under the impression we were talking about <br>
*signs*. Possibly because most of the yields I see are to yield to other <br>
*vehicles*, not pedestrians. (I *have* seen "yield to pedestrians", now <br>
that I think about it, but not sure I've ever seen *lane markings* where <br>
it's clear that what you are supposed to yield for is pedestrians. Other <br>
than crosswalks, anyway. Which... makes me wonder if <br>
"crossing=uncontrolled" is even correct; even more reason to not use <br>
that! My understanding was "uncontrolled" meant by traffic signals, but <br>
now I'm not so sure.)<br>
<br>
I've tagged some yields based on lane markings myself, e.g. <br>
<a href="https://www.openstreetmap.org/node/7714853074" rel="noreferrer" target="_blank">https://www.openstreetmap.org/node/7714853074</a>.<br>

<br>
Likewise. Even the wiki notes that this is unclear "outside the UK" (as <br>
I previously observed).<br>

<br>
As I understand it, yes, and I've tagged that in other places (e.g. the <br>
above example). I actually have no idea why that node is marked as a <br>
yield; I don't think there's actually a yield there, but I'm hesitant to <br>
just delete it (even though apparently I'm the one that added it). <br>
Unfortunately I can't go survey it right now. (Have to try to remember <br>
to do that when/if I ever make it back to that Cracker Barrel :-).)<br>
