Interesting analogy!
For instance, some cars periodically check if your hands are on the wheel. (Tesla does that, right?)
This type of check could helps confirm you are still engaged and proactively asking for consent. That would be a big step for us, we have searched the whole note-taking industry and it is very hard to find a method that is truly foolproof.
If you have a solution that wouldn't rely on pure user trust, please let us know.

Off-the-top-of-my-head... your software gets the video feeds of the other participants in the call, right? Your service could prompt people to give a simple Thumbs-Up / Thumbs-Down gesture to their cameras to signal consent (or text-chat message for those who can't gesture).
