Really? Following a law that would be passed based upon the fact that it saves lives is owning the road? Inappropriate? I'd say!
I'm obviously not referring to everyone on a bike but feel free to YouTube search motorcyclist stunting or motorcycle runs from cops or just about motorcycle anything and thousands upon thousands of hits will be returned with douchebags on bikes thinking they own the road.
As for the law saving lives, 1 out of 6 bike wrecks were the result of lane splitting. There's no way to know whether or not they would have been involved in a wreck without lane sharing, but that amounts to almost 1,000 bikes between June 2012 and August 2013 involved in a wreck due to lane splitting.
