This is an outline of each 2016 fatality that was unknown to me — or that could not be found by reverse-googling — until the database was released in mid-2017. See the full 2016 grid here.
There are 10 such incidents, not counting two additional exceedingly poorly-documented incidents that were also nowhere to be found in media report. That means that of total of 30 fatal incidents (31 fatalities, as one was double) in 2016, 18 were reported in the media while 12 were not — or at least not that I can find.
This is the kind of driving that kills bicyclists…
