...No, it's not multiple of some magical "default lane width" like you
imply. But simply _something_ between "normal" lanes=1 and "normal"

...But how can I tag you this: A road which is lanes=1+wide _AND_
lanes=2+narrow at the same time? ...You ask me to provide width and select
one of those two, and that is what I oppose, unless you give me some real
tag that is not width to tell that 'hey, there really isn't lanes marked
(which makes it kind of lanes=1) but two can somewhat fit (which makes
it kind of lanes=2 but not really because it's only "somewhat")'!
...What I would not want to do is to tag those lanes=1 because that's
certainly a lie as anyone can clearly see after observing some
bidirectional traffic there.

I oppose using width tag (at least alone) for this because it won't
convey the double meaning. Some other tag than width and tagging with
lanes=2 perhaps (like I already suggested much earlier)?
