Search for freely accessible asphalt track(s) all around Karlsruhe

Hello guys, I’m looking for a paved road where you can drive nicely (without or with little traffic). I’m thinking about drifts in rainy weather or something like this video. Of course, it should be as legal as possible. Is there a kind of register for such places? Maybe I’m just a little naive but I’m sure I’m not the first one to look for something like this. There’s probably some nice places. Does anyone have some tips? I find this a less interesting race track as it can be found in Hockenheim. It is too far away and requires too much planning (registration, etc.). LG Ric
