Did any motorcyclists get killed by a flying wheel in Final Destination? Any of the sequels? You need to learn context.
I have never seen any final destination movies. Though the context of your comment was a rebuttal to:
"Riding with no helmet in no way puts others at risk of harm."
So it appeared that you were trying to say that riding without a helmet has an increased risk of putting others at risk of harm. I don't think that the risk to others changes significantly depending on whether or not you have a helmet on.
