Hello from the Mapbox Team!
As part of on-going work to improve the quality of OpenStreetMap data, our team also fixes mapping issues based on our user’s feedback in the UK. There’s a link(https://github.com/mapbox/mapping/issues/369) to our Github ticket to the related issue. And link (https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities/In_the_UK) to our page in OSM Wiki.
This is an ongoing project, so we will continue to improve the quality of the OSM data. Edits are primarily connected with roads.
We would really appreciate your feedback, any questions you have about this project, as well as local insights that you think will help us better understand the data.
