Sometimes I have the impression that people blindly "fix" some problems in OSM. For example, I saw this:
One user traced the links without any
oneway tag and another user just inserted
oneway=yes to them. His changeset even says "Fixing motorway_link without oneway"...
If we ignore some not properly traced parts and a missing circular road on top, how could somebody fix them and not see that there are 3 motorway links with the wrong direction?
