FWIW, HH, I understand what you are saying. However, you are adding words to Forester's mouth. I had to infer about his riding style (reckless) based on his descriptions of what happened. Nowhere in his essay did he let it be known that he was intentionally riding at high speeds without yielding to cross traffic. You are saying he didn't want to make the argument that being restricted to the sidepath was unfair because he would be slower, so he ginned up this "experiment" to show that it was less safe than the road [when ridden at full speed and without yielding (which he didn't make known when describing his experiment)].
Now then, do you understand my argument? Humor me and repeat it back to me.
