All of this imagery is available immediately for use in OpenStreetMap editors like iD and JOSM. The OpenStreetMap project values "ground truth" observations as the most valuable source of information, and these photos let volunteer mappers easily verify conditions on the ground: https://www.mapbox.com/blog/id-mapillary-js/
If you haven't mapped with OpenStreetMap yet, give it a try. It just so happens that this week is OSM Geography Awareness Week: http://osmgeoweek.org/ so there might even be a mapping event near you.
However you don't need a special event for an excuse to improve OpenStreetMap - it is a very unique project in that anybody can make meaningful contributions to the project immediately. Whether you realize it or not, you are the foremost expert in the world when it comes to - your part of the world.
I work for Mapbox, maintain OpenStreetMap's in-browser iD editor (I just released v2.0.0 today!), and I've done a fair bit of streetview imagery collection for Mapbox. Ask me anything!
