I think Stonehendge's point is not that cyclists need to be perfect, but that raising standards needs to be part of the picture. The public's perception, from what makes the press, is that cyclists are always saying "this needs to change to accommodate us" and not saying "and this is what we need to change about ourselves as well."
It needs to be both, and I personally don't recall seeing any of the second message last year.
Exactly what I'm trying to say, cheers mate.
