Let's see. A cyclist plows into a runner, injuring him evidently quite seriously - perhaps imparing him for life - and you are surprised there is a lawsuit?
You make some valid points, but to be fair, it wasn't entirely clear who was culpable, or whether both bear some responsibility in causing this collision.
Whatever any legal advice is worth on this forum, it loses even that without a clear idea of the details, which are definitely lacking in this case.
However, based on what was presented, here's my considered, non-professional legal opinion of the case: It can only end in tears. (I'm not saying whose)
