No, they have talked about it in interviews. They've repeatedly said they don't have remote drivers. They have "remote assistance" that the car can call to ask questions if it's confused. You can tell when this is happening in the car, because it plays a message like "our team is working to get you moving". It's rare, maybe once every few rides. There is no way there's one overseer per car.

they did say it on record on the ars interview. one per car. and then they spin it with "they don't drive the car, just provide input".

the cases where the car halt, the system is probably waiting for a supervisor input, so it is technically 1.2 overseer per car.
