Waze is curated mostly by volunteer editors.  It went global in 2009 and they started with a basemap from paid sources.  Now after a decade and a half of tweaks by the volunteers, their maps are some of the most accurate.   Google bought Waze so they can bring that high quality map data over to Google Maps
