Good points, Blinky... I feel the same about the practice of flashing your high-beams to get attention going through an intersection...
In some cases it gets attention,.. but some drivers think you're flashinng them to signal them to go ahead...
...(I don't flash)...
What I do do,...(do do?..
),.. is weave a little bit, as I enter into a traffic light area... this helps to visually separate you from the background...
...in theory...
