I was reading this article:
It was interesting: it uses a different perspective on a the paramount problem with riding a bike- traffic.
Please excuse the cherry-picking of thought provoking ideas:
" A solo bicyclist on a road does not experience much risk (aside from steep mountain descents and other extreme situations).

That rings true.
