I signal early in anticipation of kanna blocked too. I noticed that female drivers often don’t give way. Usually are the guys who let me come in.
I usually dun look at the driver , I just see the veh as a whole.
Some of the road rage comes from having eye contacts and suggestive gestures.
So I just focus on my driving and enjoy the songs.
Even If a veh is tail gating me, I also will not look at the rear mirror to see the driver's face, I just signal and give way, I just tell myself maybe that persob is really rushing to attend an emergency situations.
