From Mr Cholmondeley-Warner's message above ...

"It's pretty routine nowadays at the scene of these serious or fatal accidents to seize drivers' mobile phones, and to have them analysed to see if the phone has had anything to do with the driving standards involved," she said.
To paraphrase - we (the accident investigators) search for illegal actions first before considering other causes of the incident.
That is, the use of the mobile phone was being treated as more reprehensible than the cyclist passing through a red light, (and not taking enough care when doing so).
This strikes me as a worrying aspect - is it now normally the case that blame is pinned on the easy target regardless of circumstances?
In similar vein I've heard that the BiB breathalyse all drivers at the scene of an incident, and if one or more are found to be over the limit don't bother searching further for the cause.
