A few car navigation apps are now letting their users report issues directly to OSM - Navmii, for example - but there's often a signal-to-noise problem: issues get logged on OSM which aren't actually a problem with the OSM data, but with the navigation app not parsing it correctly.
Or you can do what Mapbox do, which is log the issues internally (rather than on OSM) and then get your squadron of paid editors to make the corrections, but that can result in remote editors stomping on correct local data.
And then there's the new version of maps.me, which lets you edit a few things in OSM (mostly POIs) directly from the app. Pro: thousands more people are contributing to OSM overnight, which has to be good. Con: we've had people using it to persistently add Chinese translations to (say) Italian restaurants in Vienna which don't actually have Chinese names.
I'd very much like to do something along these lines, but without falling into any of those traps. I'm tending towards logging the issues externally (i.e. on cycle.travel rather than directly on OSM), but unlike what Mapbox do, making the list public so any OSMers can view it and fix the issues. Lots to think about...
(Incidentally, if you're not aware, you can now log an issue directly on openstreetmap.org without having to edit the data or indeed register; use the little speech bubble icon on the right. It helps if you do register, because then you've clicked the agreement that basically says "I'm not copying from Google Maps" - we can't guarantee that for unregistered users, so can't always take the reports on trust.)
Maybe for cycle.travel you could do something similar to the Mapbox approach but, within the UK, recruit volunteers -- after all, it is a free service to use -- who would investigate notified corrections local to them and confirm or deny them. Of course, this still relies on those volunteers agreeing with you, themselves and others, on some standardised assessment of surface conditions, and on the volume of corrections not exceeding the limits of their free time and energy. It might not be feasible, but if you think it is, I volunteer for my area!
