As many have already said, glad you are ok and will heal. As for the advice that's a personal choice. Just about everything we do has some risk involved. What's acceptable to me may not be acceptable to you. You have to weigh everything that's important to you and make your choices accordingly. You could have been driving a chevell and the same idiot may have hit you head on, who knows. The bike can be fixed or replaced so that's simple.
What's important to me is having my relationship with Jesus right so I know where I will spend enternity. So all this other stuff really doesn't matter. Anyway glad you are ok and are able to heal up from this. Now the clown in the other vehicle, that didn't even stop to help, that's another matter, he needs dealing with.
