This is not so weird, actually. The border between France and Germany goes through a roundabout between German Saarbrücken and French Forbach[0]. The French city of Strasbourg has a German suburb called Kehl. The German city of Görlitz and the Polish one of Zgorzelec are effectively one[2]. Their names are actually identical, just spelled using German and Polish rules, respectively. You might think that only provincial cities are like this, but Bratislava, the capital of Slovakia, borders both Austria and Hungary[3]. Driving from Bratislava to Vienna takes less than an hour. 0: https://www.google.no/maps/@49.2043979,6.9562696,17.39z?hl=en https://www.google.no/maps/@49.2043979,6.9562696,17.39z?hl=e... 1: https://www.google.no/maps/@48.574774,7.7601104,10719m/data=!3m1!1e3?hl=en https://www.google.no/maps/@48.574774,7.7601104,10719m/data=... 2: https://www.google.no/maps/@51.1451572,14.9916637,6742m/data=!3m1!1e3?hl=en https://www.google.no/maps/@51.1451572,14.9916637,6742m/data... 3: https://www.google.no/maps/@47.9059776,17.2954767,7.98z?hl=en https://www.google.no/maps/@47.9059776,17.2954767,7.98z?hl=e...
