Lee, I am so glad you weren't seriously injured Friday night. Always great to have help from above as you noted.
Just one thought: Make sure you don't get in any hurry signing off on the "medical release". Not encouraging any dishonest effort, just saying it takes time for some injuries to manifest themselves. I was hit from behind on an entrance ramp 7 years ago, it took over a year for neck and upper middle back disk issues to really get bad enough to get an MRI approved. It was a relatively low speed accident, but my minivan was totalled, and I think what made it so bad was that I was leaning forward, with my head turned looking back at the oncoming traffic to ensure I could merge into the right lane... The person behind obviously thought I took off, and hit the gas peddle to enter the merging traffic.... Problem was I had never moved.
