Are motorways rural or urban?
Most motorways in Germany are outside the built-up area, but there are some exceptions, notably in Berlin.
Motorways inside the built-up area have the same traffic rules as motorways outside the built-up area, because Straßenverkehrs-Ordnung §18.5 says:
Auf Autobahnen darf innerhalb geschlossener Ortschaften schneller als 50 km/h gefahren werden.
Even though it doesn't matter for the traffic rules on the motorway itself, you can use urban=* to indicate whether the road is located inside or outside the city limit signs. You can locate German motorways inside city limit sign with this Overpass query.
