My job uses OSM for route planning, and contributes back changes, road closures etc. as that directly benefit us when planning the next day. It's a great system where everyone benefits.<p>On the private, I've lately been biking/hiking lots of trails with a 360 camera, and uploaded to Mapillary as CC-BY-SA (and google street view). To make a kind of street view, but also to use the data to improve trail/mtb/biking routes in OSM. I hate planning a route and ending up having to carry my gravel bike. Or someone taking their stroller for a leisure hike on a gravel road in the woods suddenly finds out some part of it is unwalkable. Or the opposite, taking the mtb for a ride and not getting any fun. It's quite fun, a good excuse to try new roads every time I'm out just to map it.
