To the best of my knowledge, Waymo still has humans in the loop as Fleet Response agents that the vehicles can call for remote assistance when they aren't sure what to do. Caveat that the number needed likely isn't on the same order of magnitude as human drivers, but the job is likely higher paying. I could see a scenario where these should be locals for both latency (ChatGPT says SF to Miami RTT latency might be 80-100 ms and I don't believe the humans really teleoperate the vehicles, so that may not be meaningful, but that might be a bigger deal for international expansion) and knowledge of tricky intersections or road quirks in the city. They could also potentially help with labeling quirky city-specific scenarios and other various evals.
