You're restating their point but I don't think you get it. "a large number" is a vague term and I think we would be apt to say "a large number of cars run stop signs." The big issue at hand is selection and perceptual biases. If we're just going on intuition here we're going to make bad decisions. You will not notice the "large number of" cyclists that have appropriate behavior because this will be normal behavior that is non-disruptive and your brain is designed to not take special notice of this. But your brain is designed to take special notice of rare and/or disruptive events. So you always over inflate those numbers and it is hard to accurately quantify. See "Perceptual vigilance" for more.
