if lanes is about the total amount of marked "2-tracked-vehicle"-lanes (as
it is according to my understanding), then lanes=0 means no marked lanes.
No simply because 2 lanes = opposites 1 forward 1 backward marked or not.
This a routing comportement.
You can have 2 lanes but no mark on road. This is the case in rural France
road. Legaly, absence of marking is permit and you need fix right position
https://www.mapillary.com/map/im/bPYmBV9vGQr2CxoSIKGfRw this is 2 lanes
departmental road. In fact in some routing tools if there is no lane there
is no road. A lane is not in relation to road marking.
Same remark as Paul
