Thanks for the response. I'm mostly familiar with Google Docs in the workplace, where it was apparent who was reading what document at a particular moment from a list of users at the upper-right.
Separately, on my personal account, at some point I viewed a publicly shared document from a well-known person, and that ended up in my "shared documents" (or "documents shared with you"?) for ages. I wasn't sure if that sharing was evident in both directions. I've avoided clicking on shared Google Drive documents since then.
If it's not the case that the owner of the doc can audit activity, I stand corrected.
EDITED TO ADD: I suppose the root of my confusion is that it's pretty hard to distinguish the behavior of Google Drive from Google Docs; and once the lack of privacy has been observed anywhere (e.g. using Docs the workplace), it's hard not to assume it's also happening with PDF's shared via Google Drive, simply because you can't know what the other person is seeing.
It's especially hard when there is an asymmetry (e.g. in a non-GSuite environment, I can see some publicly shared document in my "shared with me" list, but I guess the sharer can't see me).
