Yes, we have some lengthy discussion on this topic in the archive. The end of it was that our track-data is not usable for this purpose but that a customized service to collect average speeds of different general car-types with drivers that are not currently mapping side-roads would be a good thing. Also many ways of anonymizing and corrupting gpx-tracks have been discussed. > - is it feasible? > - will/can derived data be used? It can be used, the license is clear. However the quality of the data is not good enough. We SHOULD get something like the map_features -page but for tags on gpx-tracks. This way we can query our tracks by vehicle-type and similar categories.
