@Caroline,
To some extent, that's the point: to arouse a certain range of emotions. Emotions, like anger and discontent, and emotions like empathy, or a sense of duty or personal responsibility. Essentially, the range of sane immediate reactions and, hopefully, emotions that develop after some thought, when you face questions like "why does this happen?" and "what can/should I do?"
You ask about the driver's remorse because you often wonder why reckless people drive. Which driver do you mean, the wrong-way driver or the suicide driver? Or do you mean all who drive automobiles?
I understand, though, about the subject angering you. Certain subjects can be revolting. I really appreciate your thoughts on the story.
