I might get down votes for this but I think it was the people who died fault. How the hell does a motorcycle do that much damage unless they are speeding. As a driver you should keep distance and check to see if a car makes a sudden stop. Especially if you are on a motorcycle you should be even more careful. The motorcyclist was an idiot for speeding down and so close of course they would die. I feel bad for them but that's because they risked their lives. As for the woman who stopped I feel worse for her for doing what was right and is a law where I come from.

Sometimes it's best to leave them alone.
