At that point, I’d expect the cyclist to pull over and let traffic flow past.

The same way we expect slower traffic to keep right or use turnouts to let faster traffic pass them on mountain roads. Nothing wrong with being slower or less comfortable on the roads, but if you are causing traffic to back up, you can get out of the way.

The biker’s loss is <1min as they use a turnout, shoulder or sidewalk, and the cars all get where they are going without needing to perform riskier passing maneuvers.

Doesn’t generally apply if you have a single car but I’ve been in a situation behind a cyclist where I wasn’t knowledgeable about the road ahead and was unable to find a place to safely pass for a while. I clearly was making the cyclist nervous, and I was nervous. A 10 second delay for the cyclist would have resolved the issue. Instead, I spent more like a minute waiting for a moment with enough visibility to let me safely pass.
