[Tagging] How to tag an imaginary oneway barrier

On the Dutch forum<http://forum.openstreetmap.org/viewtopic.php?pid=394396#p394396>there
is some discussion on how to tag a common situation.
It is about a street that has no traffic sign on one end (side A) and a C6
sign <http://commons.wikimedia.org/wiki/File:Nederlands_verkeersbord_C6.svg>on
the other end (side B) .  Ofcoarse it is not allowed to enter this
street by car from side B. If you enter the street by car from side A you
are allowed to drive all the way. But you are even allowed to drive to
(lets say) half way and then return. In other words... this is not a oneway
street for motorcars. This makes the traffic sign a more or less imaginary
oneway barrier.

Let's for simplicity's sake asume the implication of the sign is
"motorcar=no",  how should this be tagged?

The direction of the OSM way is from A to B. The options that were
mentioned on de forum were:

1 Cut the way where the sign is and use a relation type :
restriction<http://wiki.openstreetmap.org/wiki/Relation:restriction>.

2 Add a node on the way where the sign is and add a motorcar:backward=no to
this node. (similar to
traffic_sign:forward<http://wiki.openstreetmap.org/wiki/Traffic_sign#As_part_of_a_way>on
a node that is part of a way)
3 Cut the way where the sign is into a tiny piece of way.  Add a
motorcar:backward =no  to this tiny piece of way.
