> resulting in an eight-vehicle crash
I'm sorry, but this is an 8 vehicle pile up from people following too close (or paying too little attention). At least where I'm from if you run into the back of a car it's your fault. It means you followed too close, failed to react to a situation in front of you.
Should the car have stopped there, no?
But is it that car's fault that others ran into the back of it? No.
