Waymo is doing this with real, public customers (albeit hand-selected ones) in Phoenix[0]. Uber has been doing this for months with customers in Pittsburgh[1]. This is certainly a sign that Cruise is making good progress, but I wouldn't say it means they've leapfrogged the competition by any means.
