Bavarians are friendly, but they may appear rude to you, but that is just they way they are. If you need help or if you are lost, just ask. Everybody is more than happy to give you a hand. If you drive through villages, make sure you slow down. Otherwise, adjust to the more likely fast pace of traffic in Germany. Never stop on the Autobahn, especially not in the middle of road. If you missed an exit, just take the next one and turn around. The train and public transportation system in Europe is pretty good; get an offer for your next trip at www.db.de (click on the english flag or contact your local Deutsche Bahn Travel Agency).
