There is a survey being done by the University of Denver about why cyclists tend to break traffic laws. They are trying to understand the psychology behind the actions - and whether it's because cyclists do it for visibility and to feel and/or be safer on the roads. The direct link to the survey is here: http://www.surveygizmo.com/s3/1885930/bikingbad, and there's an article offering background with a link to the survey as well here: http://www.washingtonpost.com/blogs/wonkblog/wp/2015/01/09/lets-talk-serious...
