It is time to give this twofold meaning a split, into two separate keys.
Within openstreetmap it can not have a twofold meaning!
The law in many countries also speaks of double tracked or more then two
It is clear to me the new key must be double_tracked_motor_vehicle or short,
dt_motor_vehicle, or else, give it a better name.
Allready, fitted in the access hierarchy. With a OSM icon (front car)
As explained here:
https://wiki.openstreetmap.org/wiki/Talk:Key:motorcar All description and structure already indicate that a split has to be done!
(includes all double-tracked motorised vehicles when used as restriction)
this must be removed.
It is unworkable. It is a monster. motorcar=no, meaning else.
So many key conditions have to be investigated to find out what is meant by
motorcar. if and or.......is.
Working on this style/site, translating traffic law to keys/value, more keys
non motorized vehicles, what keyname, see disabled vehicles. Small groups,
maybe they have more benefits than others.
A better hierarchy structure is needed.
So the definition have to be changed once again.

Is anyone aware of other countries where these two traffic signs with
their different meanings are in use?

We probably cannot avoid defining two new keys, for example car=* and
double_tracked_motor_vehicle=*, and discouraging motorcar=* because of
its ambiguity ¬(motorcar=yes) ≠ (motorcar=no). Then, motorcar=yes can
be converted to car=yes and motorcar=no to
In the meantime, i advise everyone to tag 'no entry for any power
driven vehicle except two-wheeled motor cycles without side-car' signs
unambiguously motor_vehicle=no + motorcycle=yes (+ moped=yes/mofa=yes
if not counted as motorcycle).
