Re: [Talk-GB] Turn Restrictions at roundabouts
Could I suggest that, rather than second-guessing what some putative router might or might not do, people actually try these scenarios with one of the many real-world routers to see if they actually happen? I see an awful lot of "may" and "might" in this thread, together with a liberal sprinkling of unsourced assertions, but no actual evidence that any router has ever sent anyone round one of these roundabout flares.

[Talk-GB] Solar tagging app
Hi folks, I got annoyed with tagging the number of modules in solar generators, so I put together a quick crowdsourcing app to collect this data: https://solartagger.ru.dev/ It's definitely a lot quicker than trying to do this in an editor! Once we have panel counts that multiple people have agreed on, I'll batch insert the data into OSM using a new account - I will update this list once that is happening.

Re: [Talk-GB] Turn Restrictions at roundabouts
Surely OpenStreetMAP is about creating a MAP? The clue is in the name. So you map what's on the ground: 1. Put the flares in the right place (often they are wildly out). 2. If there is a "No U-turn" sign you add it, otherwise you don't. Making a router work properly is a job for the person making the router, not the person making the MAP.

You would also probably need a vehicle with a tight turning circle, and a quiet road - so agree it would be an unusual choice. Agree false positives. But the points about machine routing make me think maybe I shouldn't be closing these off? Any thoughts? Your example looks like a very common roundabout flare 3-way node with a cycleway crossing node. Taking the JOSM code as an example, perhaps the "ImproveOSM" validation also has a segment length test (<20m?) so the crossing is suggesting a more complex junction? Eg, at node https://www.openstreetmap.org/node/26187838 Personally, adding restrictions to this common a use-case should be unnecessary (fix once in the router, not every roundabout on the map). Save your effort for more complex junctions where software understandably needs a helping hand with real-world oddities.

Re: [Talk-GB] Turn Restrictions at roundabouts
I regularly get QA messages about this when I use the "ImproveOSM" in iD - just about every roundabout near me has at least one. I've been marking them as false positives as to my mind it's obvious that you wouldn't U-turn there (but equally, it would be legal to do so). But the points about machine routing make me think maybe I shouldn't be closing these off? Any thoughts? Eg, at node https://www.openstreetmap.org/node/26187838 Missing Turn Restriction Description 0 of 326 recorded trips (travelling west) make a turn from Bretton Gate to Bretton Gate at this node. There may be a missing "no_right_turn" restriction.
