Wasn't it a "cognitive" short-cut which wasn't (in this case) a mistake?
His self admitted general prejudice is the cognitive mistake, he states his reasons for the prejudice (cyclist filtering, road position and presence of a camera) in the OP. But perhaps he just hasn't let us know about the other times that the presence of a filtering cyclist with a camera has resulted in no incident occurring.
Later on although he used the word prejudice to describe himself in the OP he lists some statements that seems to indicate he has no prejudice at all, in fact he pretty much states he is not prejudiced and then that he is prejudiced in the same post. He even states that in the OP that his prejudice was "reinforced" by this event and then later states that he will not be "extrapolating this experience to make wider predictions."
The level of cognitive dissonance is quite remarkable.
