Bike in the middle of the road

Good day, a few days ago there was this report: http://www.wdr5.de/…/bicyclestrase-soest-jakobi-100.html I regularly drive there for a long time and get annoyed every time by the cyclists who drive there in the middle of the road. As a cyclist I would not want to drive this road or at least leave room for the cars. I spoke with a friend driving teacher, he thinks that cyclists always have to drive on the right side of the road and that drivers can overtake us. What can you do to get this roadmark removed again? Can you just report the mayor to the police because of road traffic hazards or what is the right way to get right again? Best regards, Werner Georg
