I am feeling vindicated -- not happy, but at least a little more at ease: the car guy examined my car and said that he can find no evidence of any collision. Now, I know there was one, and he knows this, but it is nice to have him report this to USAA because it is a point in my favor. How is it possible for the other driver to get hurt when there are NO marks on my car? I can't help but worry about the other driver, but I am more relaxed about it now.
