Note that Mapillary has some downsides. In addition to the CC-BY-SA license, the Mapillary T&C (
http://www.mapillary.com/terms.html 1.3) give them the specific right to reuse user content as they wish, without attribution. (This is different from OSM, which uses the ODbL.)
Also, even though the license is CC-BY-SA, section 1.2 of the T&C prohibits commercial use. Further, I see no data dumps provided (or statement of intent to provide some eventually), unlike OSM, StackExchange, Wikimedia projects.
Last, the smartphone app seems to be closed-source. (If it is open-source, I couldn't find the source.)
It is great news that people are trying to develop a Google Street View replacement, but OSM's will to let people use this data to improve OSM (like they do for Bing satellite imagery) doesn't imply that this project is as free as OSM.
