Where CoMaps obtains speed limits (lemmy.ml)

When I use navigation on CoMaps, it shows speed limits, except that when I edit my area with OpenStreetMap, I realise that the limits are not entered in the database! But CoMaps still displays them. So I was wondering where the application gets this data if it is not all taken from OpenStreetMap.

Comaps assumes some default speed limits if they are missing in osm, unfortunately it's the same value globally, depending on road type. See related issue here: https://codeberg.org/comaps/comaps/issues/1000

The values are in this file: https://codeberg.org/comaps/comaps/src/branch/main/libs/routing_common/car_model_coefs.hpp

Thanks! It was what I was thinking (ᵕ—ᴗ—) so it's will be useful to add the real maxspeed 👍
