Hi Johan,

As I understand it (1) OSM GPS routers use destination
<http://wiki.openstreetmap.org/wiki/Key:destination>=* not to compute
the routes, they can do without,  but to know what the drivers see on
the signs in order to use the same information in spoken instructions
(e. g. call a lane by its destination if possible).    Similarly for
ref=* <http://wiki.openstreetmap.org/wiki/Key:ref>   and  name
<http://wiki.openstreetmap.org/wiki/Key:name>=*.

I did not understand every word you wrote, but it looks like you want
the content of the Destination signposting.  They are all here on Google
Street View <https://maps.google.be/maps?>.  I'm not sure you can copy
the pictures, but pictures is not what is necessary for OSM: what is
written on the road signs is legal information and cannot be copyrighted.

My survey.

On E25.
destination <http://wiki.openstreetmap.org/wiki/Key:destination>=* is
not usedanywhere and ref=* <http://wiki.openstreetmap.org/wiki/Key:ref>
is *not used* onhighway
<http://wiki.openstreetmap.org/wiki/Key:highway>=motorway_link
<http://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway_link>.
Hence, *there is no name to use* for a GPS to call a motorway entrance.
For motorway exits, such a ref is useless but ref=*
<http://wiki.openstreetmap.org/wiki/Key:ref> is used all-right on
highway
<http://wiki.openstreetmap.org/wiki/Key:highway>=motorway_junction
<http://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway_junction>.

Shouldn't the same ref=* <http://wiki.openstreetmap.org/wiki/Key:ref> as
of the motorway be used on allhighway
<http://wiki.openstreetmap.org/wiki/Key:highway>=motorway_link
<http://wiki.openstreetmap.org/wiki/Tag:highway%3Dmotorway_link>?


On other major highways.
name <http://wiki.openstreetmap.org/wiki/Key:name>=* is used but the
driver sees no (real) signs (plates) for it.
ref=* <http://wiki.openstreetmap.org/wiki/Key:ref> is almost always
present but the road sign (e.g. N30) is sometimes missing on the ground,
which is annoying for the driver in a roundabout or at the fork to two
main directions.

I tried to contact the MET to report a few such cases, but they did not
reply.
*Does anyone know* how to signal the MET their mistakes or should we tag
for the minister?

Let us think before such an extreme outcome :-)

I'm not a lanes specialist, but it seems to me that lane drawing
topology is enough for routing software to know and tell the driver
which of the lanes (n°1, n°2, n°3) to take to get to another lane ahead.
So, the question is: what should the GPS tell the driver (click, choose
language, click loudspeaker):

  * That  ???

Is it really necessary to make a mess by trying to spell/translate every
place in/to every language (2)?
Isn't it wiser to use only the (ref) numbering system devised and used
for everybody's convenience?
That's including OSM.
I think that just the destination:ref is necessary, and only if it
cannot be derived from topology.
The names on the signs are for those who drive without GPS and as a
reassuring double check.
Or in the rare cases there would be no refs.

It worked ;-)

(1) they can do without them. This is unfortunately badly explained once
again.
(2) I usually listen to Osmand in English.
Easier to understand (must be my ear too) and sounding like navigating
to the moon (add beeps).
But the real fun is trying to understand French names pronounced à la
English !!! :-)
