There are few ways of entering the upper mentioned motorways:

Just 30 minutes by Regionalbahn (train) south west of Berlin. You easily get hitches to the south or west as well as to the east (Poland). Take a train (e.g. RE7 to Dessau, check fahrinfo-berlin.de for route information) from the center (ABC 3.10 EUR). Get off at the train station Michendorf. Leave the station at the left side (in direction of the train). Turn right into the Potsdamer Straße, at the bus stop, and walk for 20 minutes straight on it. To go west or south (Magdeburg, Hannover or Leipzig, Munich) turn right into Feldstraße and follow it till you see the service station. Enter via the green emergency door. Alternatively you can get here by bus 643 or 608 from Potsdam Hbf which also passes the train station in Michendorf. Get off at "Michendorf Abzweig Wildenbruch", and walk south west for the final stretch to the service station.
