Does anyone even check what HOTOSM contributors leave behind? 8 months ago

It is not only a problem of new mappers. This Problem is in deed very HOT specific. HOT is encouraging new mappers, to map places, where nothing is to find comparable to their normal environment. And in some boring tiles, where nothing is to map, even experienced mappers start to map animal traces as highway=unclassified. Project managers and requesting organisations are most of the time neither involved in mapping nor in validating. No critical feedback, only success stories all the time.

Second: It is simply extendable with common tags and therefore it it much more versatile as this aged zombie proposal. And by the way, simply counting relations and ways is like trying to compare of apples with oranges

As mentioned before, there is already an approved way to map turnlanes in osm. This scheme is also supported by osmand and mapfactor since some time.

Hallo 4gruwe,
wäre echt schade einen so aktiven Mapper in direkter Nachbarschaft zu verlieren.
Falls du dich an meinen Edits gestört haben solltest könnten wir das auch vor Ort klären.
