If this is your iPhone, Waymo support told me they’ll be sending the car to the depot. There was no identification in the case, so I’ll let them do their thing in returning back to the owner. In SF.
If I remember correctly, there was a post a while ago where someone did go to the depot and was unable to get their stuff back.
Hope you get it back to whoever this belongs to!
