[Tagging] Sample tagging for highways with no lane markings

You have other tags to mark there is more than one direction:
oneway=no

I think it is important to  keep the sense of the wiki, why?
Because , with data you can "imagine" (or render) some kind of reality. It
is not the same:

1
oneway=no
lanes=1

2
oneway=no
lanes=2
https://www.mapillary.com/map/im/xg8szNBm0vd2ESAkjds1DA

3
oneway=yes
lanes=1
https://www.mapillary.com/map/im/OxpRJfW_9qy_Z8QL4NoWXw

4
oneway=yes
lanes=2
https://www.mapillary.com/map/im/oENxpXhruhvcFszNlkudtg

Think about it : with more than one lane you can overtake legally. With
only one lane you cannot overtake in your same direction because you don't
have any lane to pass by. If the streetof only one lane is wide enough you
can pass a stopped car, but you cannot overtake it if they are moving also.
Ask it to the police. I think is interesting to keep the meaning of the
tagging scheme.

May we have to retag all the oneway=no without lanes all over the world?
May we have to add a new tag called divider (or similar?) . For me if
divider=yes lanes > 1 , if divider=no lanes = 1 so I don't need a new tag
to remark it.
