In latest MTB-maps e.g. https://www.seeundberg.at/user_upload_BKK/user_upload/Dokumente/Prospekte/Bikekarte_MBN_2024.pdf this MTB-Tour is still complete. And there's also no No-driving sign

So I'll keep  it at it is. Otherwise you should open new notes at places exactely where u think it its forbidden
