I cut up the A1 at every exit that connects to a "Bundesstraße", but
really it's about the editing that is helped by shorter ways.

While it's correct that the signs may overlap it is very wrong to leave
out the ref tag on one of the ways, because a routing application
wouldn't know. So for correct maps always tag every way of the motorway
with all important information like highway, ref and name (if applicable).
The resulting ugliness can and will be worked out in the renderer, don't
leave out names on ways just because it's ugly, and that isn't limited
to motorways either, but to any data entered into OSM.
if you have some ugly names showing in segments of road where the name
shouldn't be rendered, put a tag like "osmarender:renderName=no" instead
of leaving it out.
