Riding on Busy Roads - Avoiding Close Shaves?

Have been working on the new National Standards Level 3 Syllabus,
this is a resume of the compulsory points that simplifies things, basically what most of us are doing every day. These can be read and translated into action.

Holding a line. Maintaining effective transit.
3.1 In busy traffic as a prerequisite no weaving, entering /leaving gaps at side of road is understanding advanced road positioning, being a road user with same status as every other.
4.0/ 6.0 Passing queuing traffic (filtering) always on right side. 3 reasons for this:- drivers unlikely to open right door, avoiding blind spots, 360 degree view of whole road.
5.1 Where road narrows ahead, checking back, taking lane in advance if necessary.
4.3/ 5.1/ 5.2 Where right indicating turning vehicles are stationary, and moving traffic feeds through narrow gaps, checking back then taking a place in that traffic stream.
5.1 When passing side roads, checking back, taking the lane to avoid fast exiting vehicles.
5.2 When lanes split like V’s ahead, checking back, taking lane and advanced line in your direction.
7.0 Avoiding poor road surfaces, gutter cycling.
Bicycle Body Language. Behaviour breeds behaviour, how to get given equality on the road.
1.5 Gesturing acknowledgement on approach to buses indicating immanent departure from stops.
4.6 Anticipating traffic lights changing back to red from green, freewheeling whilst maintaining primary position and place in traffic stream.
3.2 Maintaining place in traffic stream 3 or 4 vehicles back from traffic lights.
Face use, direct eye contact moving at speed of traffic.
Acknowledge other road users who yield space at points of congestion, junctions or roundabouts with queuing traffic streams.
Give acknowledgement when flashed for moving position on major to minor road junction turns.
