Not sure I believe this. Obviously it's a fuzzy statement but I don't think I've ever once in my life seen someone blatantly ignore oncoming traffic due to having an unprotected left signal.

Any one driver's experience is necessarily extremely limited, a tiny fraction of a fraction of a fraction of all miles driven or traffic lights stopped at. You not having seen that happen should not be expected to be representative at all.

I have seen that happen, though fortunately there was enough time for both drivers to avoid a crash.
