As of last summer, DC's system had its 7 millionth ride, and at least as of that time, there had been no fatalities and only one life-threatening injury (see http://www.washingtoncitypaper.com/blogs/citydesk/2014/06/03/there-have-been-95-reported-crashes-on-capital-bikeshare-since-its-launch-2/ http://www.washingtoncitypaper.com/blogs/citydesk/2014/06/03... ). As far as I know there have been no deaths since, either, despite virtually no users of the system wearing helmets. The actual risk associated with helmetless riding, and especially helmetless riding on bikeshare bikes, is dramatically overblown. Speeds on chunky slow bikes in an urban context are simply not high enough for accidents to be likely to result in serious injury.
