The evidence I mention is very clear and has been very widely and repeatedly reported. A very high proportion of these deaths over several years resulted from the cyclist being in the blind left spot of a truck at a junction."The evidence is that almost all of these accidents was totally under the control of the cyclist and could easily have been avoided by them." Where is this evidence? Did not the latest stats on cycle accident reveal 68% of KSI collisions were the fault of the driver?
The two things you state are disparate so not relevant. By avoiding a position of danger a cyclist can avoid an accident that would have been the fault of someone else if it had occurred. I've been successfully doing it all my cycling life.
Therefore those accidents were under the control of the cyclists and could have been avoided! The message is clear:
Avoid riding alongside the nearside of trucks at junctions.
