It’s not furious, but it is fast. The Autobahn, or federal roadways in Germany, Austria and Switzerland, are amazing pieces of engineering and speed.
Question: Can you see four countries in Central Europe in four days? Why yes, yes you can. I recently came back from my Central Europe road trip that covered Germany, Austria, Liechtenstein, and Switzerland.
My travel buddy and I hit three major cities and three smaller towns/cities, as well as ate delicious food and saw many amazing sights. Going in winter also gave me an appreciation of how busy these places are on an off-peak day.
