Hello mapzania. Why do you move real objects? For example:
https://www.openstreetmap.org/node/3667139765
https://www.openstreetmap.org/node/3469892127
Do you see this road signs on the aerial imagery?
I'm a local contributor and I added these signs using gps-coordinates. Are my gps-coordinates bad for you? -

Hi mavl! Thanks for your contributions, the area really looks great! I was just aligning this highway to Bing and OSM GPS because it appeared to be slightly misaligned. I was aware of the mile-markers and made sure to keep them at the same distance along the road so as not to change the location where you added them. Moving them was just part of aligning the road. Here is a summary of the changeset: https://overpass-api.de/achavi/?changeset=59165521. Hope this helps!

Thank you for your answer. Unfortunately, there is no absolute accuracy.
The node [https://www.openstreetmap.org/node/3667139765/history] is moved by 3.5 m and by 1 m along the road.
The node [https://www.openstreetmap.org/node/3469892127/history] is moved by 7 m and by 5 m along the road. The other nodes is moved by 6-9 meters. This is very close to the limit of OSM accuracy. The usual gps-navigator has an accuracy of 5-10 meters. The width of this road is 7 meters. So this moving does not improve OpenStreetMap almost.
Probably, you think that I'm a capricious man but I read OSM wiki about it:
[https://wiki.openstreetmap.org/wiki/Editing_Standards_and_Conventions]
[https://wiki.openstreetmap.org/wiki/Accuracy]
I have reverted one similar changeset several days ago [https://www.openstreetmap.org/changeset/59090846]. I'm not going to revert this changeset. Good mapping.
