I watched a documentary about the Brain recently in which the limitations of what we can see, was explored. Surprisingly, one example was cars making left hand turns and why they do not see motorcycles. The explanation given was due to what we are looking for (which are 4 wheel vehicles) and our minds limit that search (not looking for 2 wheeled vehicles). “When drivers say they didn’t see you, their brains really didn’t”. Other experiments were shown to illustrate the point.
I agree with attracting attention at intersections by weaving the bike and making eye contact. I haven’t but might consider switching on the high-beams and leaving them on.
What I am nervous about is flicking the lights because I believe that is a sign to defer, giving the go ahead to the other driver to proceed. Use with caution.
Good Post. Thanx
