I now have a letter (here and here) from an Acting Deputy Chief Crown Prosecutor which essentially reiterates the rejection of my complaint by the District Crown Prosecutor. The Acting Deputy Chief says that 'there is no evidence that Mr Stead's error of judgment was so substantial that it caused the driving to be dangerous'. So there is now a total of 4 prosecutors who do not appear to recognise that attempting an overtake that could not be carried out safely and failing to have a safe and proper regard for vulnerable road users are not merely evidence of dangerous driving but are 'likely to be characterised as dangerous driving' according to their own guidance.
There is no explanation from the CPS as to when an 'error of judgment' (nice comforting description of bad driving) is 'so substantial' (big, big hurdle implied) that it causes driving to be dangerous. Even directed specifically to their own guidance, drafted in large part to deal with undercharging, the CPS en bloc substitute their own motor-centric ideas of 'errors of judgment' needing to be 'so substantial' etc. This was not a case of momentary inattention or distraction, Mr Stead chose to try to pass me on my bicycle with his very massive HGV on a narrow road when traffic was coming the other way. It was a deliberate act.
It will not surprise you that I am not happy with this letter and have now written to the DPP here
