Do we know that the remote operators (all? mostly?) show up in that data as employees, though? Waymo's development has presumably reached the point where it would want to start filling remote-assistance seats with contractors. (There's also offline but relatively labour-intensive work like updating maps, adjusting routes and the like.)

One remote assistant per 50 or 100 vehicles would also seem to put Waymo now far ahead of where Cruise was in 2023, when according to the NYT's sources Cruise's remote assistance staff "intervened to assist the vehicles every two and a half to five miles", though I suppose it's not especially hard to believe that 2025 Waymo is beating 2023 Cruise handily.
