I would think it would be a challenge to get useful data from such a source even if resolution were high enough. That nice low traffic road may have been photographed in the weekend, outside traffic hours, on a national holiday, because of a road black a kilometer away, etc.
for other traffic related datasets, check out this list: https://github.com/graphhopper/open-traffic-collection
and for "borrowing" the live data from TomTom, check out this mini tweet thread (from me): https://twitter.com/philshem/status/1241739025624567813
It is unclear to me whether their current practice is in harmony with the Google Maps TOS. For some places there are also open traffic data sources: https://github.com/graphhopper/open-traffic-collection

TomTom, HERE and inrix. All acquire their data via external software companies or automotive companies (or whatever) including their measurement units into their products.
Mapzen was starting their open traffic data project and so we at Graphhopper were hoping they would solve this issue in the next years, but now, obviously they won't:
