Hello,

I see that you used the tag `lanes:unmarked=yes` here to denote the lack of lane markings. Currently, there are only 515 of this tag in the world, in contrast to `lane_markings=no` which has over 1.4 million. Also, the latter tag is documented on the wiki, while the former is not. As such, I would recommend using `lane_markings=*` for this going forward.

The two most common values for `lanes:unmarked=*` is 1 and 2, so perhaps this tag is usually used when some lanes are not marked while the rest are. Even still, this is a much more obscure tag than `lane_markings=*`.
