Separate shield for Hungary primary routes about openstreetmap-americana

[attilakundev]

I forgot to add that there are also some trunk routes which start with M, which can be seen in this list.
https://hu.wikipedia.org/wiki/Sablon:Magyarorsz%C3%A1g_aut%C3%B3p%C3%A1ly%C3%A1i
Autópályák = Motorways
Autóutak = Expressways
the rest isn't interesting because they are only either planned or they are dropped plans.

The only important thing is that those which start with M are blue (M3, M25 etc), the rest are green like 3, 24, 222.

In Hungary, there are two separate shields for motorway and primary routes, however they use the same network value. Motorway shields use a ref with an "M" prefix. Since these shields are the exact same style, just with different colors

Has anyone considered creating separate networks of routes that connect? This approach was taken in Vietnam (#190) for essentially the same situation, and it hasn’t led to any problems that I’m aware of.

Currently this project gives all network=HU:national routes a blue shield, even though most of the relations are main roads that should have a green shield. We should remove support for network=HU:national until there’s a way to reliably distinguish the two networks.
