Talk about lazy journalist, 95% of this article was in the paper or a local ABC story before. The author simply added the latest killing of cyclist story and maybe the idea of the arm bands is new. BF discussed the previous article as well, particularly noting the "For bike riders, unsafe speed was the most dangerous violation" BS.
Edit: It may have been this thread, on a local ABC story that is no longer available, but was based on and referenced the almost one year old analysis by The Chronicle.
