Are you sitting down? Because I'm going to rock your world right now. It turns out that there are - brace yourself for this - inherent risks involved in riding a motorcycle.
According to the landmark Hurt Report, the left-turn-in-front-of-the-motorcycle is the most common two-vehicle motorcycle accident, and one where the motorcyclist is generally not at fault.
But most of the talk is of Roethlisberger's irresponsibility, not of the driver who hit him.
When can we stop talking about this? If you don't want to wear a helmet, and it isn't against the law, don't wear a helmet. Endangering others is one thing, but sometimes there are no laws against being a freaking idiot. Irresponsibility on his part is none of anyone else's f&#$%ing business.
