Alas, we can't do what Google Maps does, and aggregate the private information of everyone carrying a cell phone to measure current traffic speeds. That appears to be how Google's router makes its decisions.
Of course we used to have something along those lines with Strava.... RIP. Smaller-scale but still useful -- The rideshare company Juno, which uses OSM data for both routing and map display, shares a rolling aggregate of their GPS traces which can be enabled as a layer in JOSM. No doubt it could be algorithmically cross-reference with road classification; I've just been inspecting it visually. Juno only operates in NYC for now, and the data has clear demographic limitations (it shows which roads are priorities for the kind of people who either work for or use rideshare services). But it actually covers the city's grid pretty well, and I've found it useful. (See https://lists.openstreetmap.org/pipermail/talk/2019-March/082303.html ...also there were a couple Maproulette challenge using this data to spot incorrect one-ways, bad turn restrictions, missing connections, etc, see https://lists.openstreetmap.org/pipermail/talk-us/2019-February/019210.html https://lists.openstreetmap.org/pipermail/talk-us/2019-February/019224.html ) Note that this didn't require a bunch of end-user data consumers to install an app which shares their location data with OSM. Obviously Juno's customers do install the Juno app, but the shared data comes from the driver's app, not the rider's. Also note that Juno's decision to share back to OSM in this way was entirely optional -- I don't think any reasonable interpretation of the ODbL would actually require this. Nonetheless it's a nice precedent, and if other companies that consume OSM data chose to give back in this way it would help. (Of course the trigger for this whole process was the fact that OSM's road and address data in NYC was good enough that it was a reasonable decision to use it in a business setting!)
