OK. I removed the tag barrier. May somone delete the lines or improve it. Thank you very much for the input. I like it when people criticize me in a positive way.
This area ist mapped very good anyway. 
There are still so many areas left where rudimentary things are missing. Today I was in Bietigheim-Bissingen. There are still missing connections and some details. And sorry for my "google-english" ;-)
