I'd map as if full .. this would be the area used by the bicycles and
not all ways available for other use.

Um .. what is 'left' ? :0 And why do we need to map it? As cyclists can
see (I hope) then they should readily be able to determine the access path?

Polygons are better than lines, has they more information and are more
Some mappers may map a line at the bicycle fixing point, others might
map the line at the bicycle half width point and some others elsewhere.
