I am glad you are okay. From the looks of the pictures, I feel someone was looking out for you that day.
I don't believe that you have to settle when the insurance company wants to when you weren't at fault. They have to wait for all of your medical issues before they can force you to do anything. Plus you might have things come up later, with back problems or something.
Anyway, I hope you continue to well and recover quickly.
Do you know if he said anything about not seeing you or what his excuse was to continue when you were coming? Did he think he could beat you, or just didn't care? I know it shouldn't matter, but I would want something from him that acknowledged what he did and how bad he screwed up and that he could have killed you!!!
I don't mean to sound harsh towards him. I'm sure he did not mean or want to hit you, but if he shows no remorse then he has learned nothing from his mistake or impatience or whatever it was.
