Please excuse me for being so curious, but why are you doing this? Just driving around or do you visit relatives and friends or do you have special places for holidys you are going a few times a year? I am sorry for my !DERANGED questions, but now you have made me curious.
The german highways (Autobahn) are the fastest in the world. I know, there are construction zones as we do have them too, but it cannot be that bad, but you must know better, because I haven't been north of Austria for quite a while ;)
I wish you a great day too @wakeupkitty 🙂
