Not from what I've seen - it happens in real-time just like most human drivers. I don't believe that a remote controlled operator is even permitted, but I could be wrong.
Waymos drive fairly fast and aggressively in rush hour traffic too, which is why I enjoy sharing the road with them. I was initially worried they'd drive like a grandma but that hasn't been the case. Also as a cyclist I enjoy riding near them because they know I'm there and they give you enough space in the bike lane.
