I live in Poland. Every car radio I have ever owned did this, and every station that is available on more than a single frequency (that I'm aware of) can be followed using RDS. I can also listen to a CD or other media [1] and let it scan for traffic news in the background, it switches to any station that currently airs traffic news. It held true on road trips to other European countries.
[1] I rarely do this, for me listening to radio is an integral part of driving. Especially when I have commuted to/from work, I was able to tell if I'm running late based on what segment has been airing when driving past particular intersection or landmark.
