I've noticed that someone from the Microsoft Open Map team is very busy adding turn restrictions all over the place ( https://www.openstreetmap.org/user/shawat94/ ).
In my local neighbourhood, I noticed that he added no_u_turn restrictions to all the nodes where a road into in/out of a roundabout is splitting (because of physical separation). Which basically amounts to 4 no_u_turn restrictions for every single roundabout. e.g. here: https://www.openstreetmap.org/changeset/57747093 https://www.openstreetmap.org/changeset/57674063 There is no actual no_u_turn sign in any of these locations, it's just (mostly) physically a bad idea to attempt a u-turn here. Just a few weeks ago I discussed exactly this in #osm and the conclusion was that it was neither necessary nor desirable to do this. I made a comment about that to the first of the two changesets linked above, but haven't gotten a reply. So, what is the general opinion about this here? Should these turn restrictions be created or not? Cheers, Thorsten
