I agree, they have remote drivers waiting to take over, but I think that the current SOA is delivering a very high % of autonomy. Is this viable? Dunno... Will it creep up? Dunno...
you have no idea how much they drive. they avoid talking about it on every interview. Ars explicitly called then out on this and they called saying this is their main profit sucking issue right now "having one overseer per car". to me that means they are, for all practical purposes, driving. no matter how much they try to spin it.
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.
