The pinch point - again = back to COAST and in particular - S and T.
Many misjudge the the time it will take to pass the cyclist - and cyclists do not help - as I have noted they tend to increase speed at these points. Part of this is actually understandable as
1. They are aware that by adopting a correct and high profile road position - they feel vulnerable and aware they may be holding up traffic
2. They wish to get through the danger zone themselves asap.
(I do confess to wellying up my pedalling power at such points as I dislike them myself - as cyclist and driver - and I've had the "enhanced bits - I can ride a bike up steps now!
!
Lot of cyclists also forget the importance of gears and braking too - bike gears are just like car gears - part of the handling and control techniques. Lot of these bikes are very high tech these days - you can actually get a nice healthy speed on them . It's part of the fun though.
I would agree that some of the answers are a bit "iffy" - one I think should be "varies" You maximise your road presence and that implies an element of variation.
The CTC has produced some reccommendations to set a National Standard - and objectives are to ensure 60% 12 year olds have a Cycling Proficiency certifificate by 2006 - (not happening in many areas! Funding!) and courses aimed at adults. (again not happening)
IIRC The scheme has been piloted in 4 areas of the country and IIRC - started in 2002. Long pilot scheme then!
