When I started riding 25 years ago; that's one of the first things I learned... GUARD YOUR LANE! If you don't, other drivers *WILL* try to "share" it. The ONLY time you don't do this is when it poses a direct danger to you... To the OP: Hope you heal up quickly. I would certainly get a lawyer involved ASAP. The Cops will likely NOT do the right thing for you... it's less paperwork for them.
