3G is switched off in Germany but providers are required to continue to support 2G specifically for emergency services so the dumbest and oldest phones can understand them.
I think RDS is or was mandatory in cars, too, the whole EU is switching over to DAB+ though and that's the only thing I could find articles about. Much better anyway as RDS would simply send a signal saying "interrupt the cassette, a broadcast is coming in" and then someone would rattle off traffic jams or "people are throwing objects from a bridge", while DAB+ broadcasts way more data which can then be interpreted by the navigation system, which can then rattle off everything that's actually relevant to you.
