Cyclists have no duty to "move into the breakdown lane" so that a vehicle can pass.
Whether you're trying to pass a slow-moving automobile, truck, motorcycle, bicycle, or, whatever the case may be, it's YOUR responsibility to find a safe and wide-enough place to pass safely without endangering yourself or the person you're passing. I say that with all due respect.
I've learned this in my years as a sportbike rider, when, often times, on a mountain road, I'll find myself stuck behind slow-moving cars, trucks, or Harleys. Even groups of cyclists at times. And, you know what? Usually if you wait 5 minutes, whatever's holding you up will turn off, or, you'll come upon a safe place to pass.
Calling cyclists "jerks", etc, is a manifestation of your own impatience.
