I definitely agree with this statement, as my mindset is that I'm the only one looking out for me, and ride very defensively.

The intersections are odd where I am in Oregon (south Beaverton/north Tigard). Many times only 1 left turn arrow will activate at any given time. The times I arrive at this intersection the left-turn arrow goes green in my direction, then all traffic gets a red light for about 2 seconds, then my lane and the opposite lane through traffic gets a green, then a few seconds later both lanes get a flashing yellow left-turn arrow.

Whooo, glad I posted the picture than tried to verbally explain this deal!
