There was a proposal for tagging type of divider, but it has been abandoned
for several years:

There is also a proposal for a relation to unify dual carriageways
(e.g. often pedestrians can cross but cars can't, dependent on the
kind of divider) which also allows for tagging of the divider (either
implicitly or explicitly):

How would you tag a lane according to this proposal that allows at the
same time e.g. to go straight and left?
Lanes separately are not tagged, only lane groups. In this case there are
one lane group for turning left and one — for going straight. So it would be
lanes=N, lanes:turnleft=1, lanes:through=N. If the left lane was used _only_
for turning left, lanes:through tag could be omitted.
how would the data consumer know, where the lanes are? E.g. a lane to
turn left might also be right of the through-lanes, and this is
crucial for routers to give good indications.
When we already have numbers for the track positions, why we do not use
them thus? So the data consumer knows the location without the
lanes:location tag.
lanes=4
lanes:turnleft=3;4
lanes:merge=1
lanes:through=2;3
