The DL in Germany is ridiculous expensive but at least after you went through driving school and all the testing, you know basics to drive a vehicle properly, even in difficult situations. I am certainly glad that you can not just get a cheap license somewhere and show up in Germany and they will match it right away so that the applicant was able to save all the "hassle" to go through learning to drive. Once you have been on the Autobahn or in a "sign forest" (Schilderwald), you will be happy that you learned how to drive properly. Each country drives differently and I am always happy to get some guidance if I stay there for a longer period of time. Of course, just for vacation, it doesn't matter that much
