Selective use of the quote button by several posters again... as usual...
Perhaps you should drive that section.
On a wednseday evening..
Then decide if its acceptable that riders and organisers act and cycle in the manner they do.
It has nothing to do with the improvement of drivers but the complete unsuitability for this to take place where and when it does.
So what is a safe speed for a dual carriageway, national speed limit road then?
A road that sees HGV's at 56mph.
Cars at 70mph.
10? 20? 30mph?
Is it both acceptable and SAFE for cyclists to be on that section of road?
At a peak time?
Competing in a time trial.
Or even on that section of road at all.
Police have been involved before now because of cyclists swerving out.
I love how its always the drivers fault here.
Of course the cyclists can't possibly be wrong now can they... 
Can't possibly be the one guilty of riding without due care and attention.
Guilty of poor lane discipline.
Guilty of failure to give way.
Etc.
Etc.
Etc.
And you want an automatic presumption of liability in these cases?
You can look a long way ahead, use good positioning and all the tricks you want to drive safely and considerately, overtaking safely, when safe to do so, etc but obviously certain riding gods think its perfectly ok to ride on a major A Road without consideration of the RTA1958, Highway Code and other road users but other road users should put them first.
Funny as it seems to be the ones that admit to RLJ and other stuff as fine when that pops its head up too thinking that this behaviour is ok.
As far as I'm concerned - the sooner cyclists are held liable for their actions when on the road in the same way all other road users are the better.
What makes them exempt from having to obey the rules the same as everyone else?
anotherdeadhero - you don't know me so I'd suggest winding that neck in of yours unless you can speak from first hand experience of this particular road.
Can you?
