Update 2016: Although the B2 starts right next to Wittenberg's Old Town, it's nearly impossible to get a ride from there, as the driving speed starts already at 100km/h. There are not any crossings, roundabouts or bus stops where the drivers could possibly reduce the speed to pick you up. The first actual place where you could stand with your thumb up would be Eutzch, a little village 9km south from Wittenberg. You can walk there (it's a long walk and there's a sidewalk only in the first 5km) or take the bus 306, which runs from Wittenberg Hauptbahnhof once every hour. From Eutzsch you should be able to get a ride to Leipzig within a few minutes.
