I'm taking a look at traffic circles like this:

https://www.openstreetmap.org/edit#map=19/33.790043/-118.142392

The main traffic circle has been split up into 8 different segments, so that individual segments can have Relations added to them, such as the "Long Beach Transit 174" bus route. I'm new to mapping, so I don't really know what to expect, but it seems odd to split it up like that. It ends up adding noise to StreetComplete, in that I can't just say "yep, this traffic circle is asphalt", I have to go to a bunch of tiny segments and mark each one of them as asphalt.

I've also seen this for items generated from Lyft data, where a single road gets split into tiny segments so that one part can be marked as "no u-turn" or "no left turn". StreetComplete wants me to mark each tiny segment individually.
