In reply to wilkesley:
Was it particularly bad weather yesterday? only this happenned at lunch time, not rush hour, and not at night.
Given the position of it (and not knowing him or where he was going) it is a bit of a leap to think he is aware of the small lanes near by - which looking at the map here (is this the right spot - it's not even a dual carriage way?)
http://goo.gl/maps/eIrFk don't appear to be remotely parallel to the main road. Or does it mean this road:
http://goo.gl/maps/gkv4Q a bit further along (noting the reference to Whitchurch in the article), where it's not even marked as a main road on the map
In fact I have riden very similar roads in that area when doing LEJOG (although I don't think that one). If you are out of area, you are unlikely to know that a road has high accident rates or that there may be a better alternative.
I hope they catch the lorry driver
