Hello mboesch,

In this edit you have added a "motor_vehicle=no" tag to
https://www.openstreetmap.org/way/815229018
and
https://www.openstreetmap.org/way/430861991

Both ways were, and still are, tagged with 
" tracktype=grade2", making them suitable for standard vehicles.

What is the source of this change?

Best Regards,
