A cycle awareness section is no good unless all cyclists stick to the same rules of the road.
Marla and Tracy have hit the nail on the head - you never know what they are going to do!
Even I am often at a loss as to how to communicate to another road user what my intentions are when there is no procedure laid down.
e.g. peddling
up a steep hill on a cycle path, when a vehicle appears at an exit (driveway from a small industrial estate).
I am on their left, and to their right is a brow of the hill, from which vehicles appear quite quickly.
How do I indicate that I am not going to get there fast, and that they should look out for themselves, because the worse that can happen for me is that I will have to drop back to 2mph instead of 4mph?
I have tried waving them out - only to have them think I was waving them back in out of the way... then having to wait for me to get there and pass in front!
I now resort to trying to tuck back in out of their view, so that they can concentrate on the real hazard - the vehicles approaching over the brow on their right! I then extend a hand, palm upwards in a sort of "after you" gesture!
