With Mr. Issakove's permission I am reprinting his thoughts:
I think that it might be effective to further our cause by presenting the safety advice given to motorcyclists with respect to lane positioning, and then to ask the question; "If this is good advice for motorcyclists, why is it not good advice that bicyclists should follow?"
The only plausible and reasonable response is "Because then they are going to get run over from behind, because they are so slow". Once they have articulated this, then they are more likely to seriously consider the evidence against that position.
After that, all that they have left is, "I don't care if it makes cyclists less safe, they need to stay out of the way." Perhaps I'm naive, but I believe most people don't realize that this is, in the end, their position. If they can be made to see that they are holding to such a callus position, we will have an opportunity to change it.
Most people seem to honestly believe that the reason they are justified in believing that bicyclists should be out of the way is because bicyclists are unnecessarily endangering themselves. So, one way or the other, we need to convey that bicycling "out of the way" is often more dangerous than being "in the way".
That's why I think it's important to emphasize the dangers of riding "out of the way". Presenting the safety advice given to motorcyclists, and then asking your audience to consider the reasoning behind that advice. Why shouldn't these principals also apply to bicyclists? They do apply to operating a bicycle, and ought to be applied to our craft.
