Luxembourg is a picturesque country. I found a tip to drive in Europe. As long as I can pass through Germany, I will try to walk from Germany. No high speed! Charge! Fee! And no! Limit! Speed! And oil! Price! Low! It is definitely the cheapest country in Europe for road travel. The leftmost lane in other countries is reserved for vehicles with more than one person. In Germany, the leftmost lane is reserved for Mercedes-Benz BMW Audi. Do your best to let you drive. Ordinary cars can drive on the leftmost lane. I lose hahahahaha, I never understood why the dashboard of the car had a 180 km setting. In Germany, I suddenly understood hahahahaha.
