I managed to hold my anger and frustration in almost every situation in life except for this one. You just can be easy seeing an accident in the making and you are forced to be part of it.
Worst is when they see you have no way to the right (or left) for them to take you over.
Like seriously, what do you want from me? should I just disappear?
My current reaction? I immediately start the flasher and either keep my speed ignoring whatever they do until they increase the distance and give up, or start slowing down until I have a way to let them over take me.
