Not in other languages. In German, for example, it would very weird to think of railroads (Bahn/Eisenbahn/Bahnstrecke) as roads (Straßen). Would you also claim that a hedgehog is a pig?

But autobahn is a road, no?

Yes, but "Bahn" actually means "track", "path" or "lane". "Bahn" in the sense of "railroad" is an abbreviation of "Eisenbahn" (literal translation: "iron tracks"). So "Autobahn" has nothing to do with railroad, it just means "car track".
