(Assuming that is even true) 50 lives a year, how pathetic.
Quite. Total speeding fines by camera are over £1 billion.
DfT are saying 100 lives per year based on 'at camera sites' figures
before regression to the mean (RTTM) correction. (Based on 42% reduction at speed camera sites, and about 240 deaths per year 'before' at speed camera sites. 240*.42 = 100)
With RTTM correction (50%) (240*.5= 120) I believe that the true figure is an INCREASE of about 20 deaths (100-120) at speed camera sites
and 1,200 elsewhere due to side effects.
