Being born in 1980, I can confirm that this TV show is German, aired on German TV, and aired in the 1980s. Everything about this show is authentic, especially its racism. 1980s Germans were exclusively racist towards foreigners they perceived as weaker, never towards obviously bullying foreigners. Italians, Eastern Europeans and Greeks are welcome targets if you follow your 1980s German rule book. Even that part was pleasant to watch because - that was what Germans were and what they strived to be. Germany being located in the centre of Europe is probably destined to shoot this kind of pan-European trucker show.
