Thank you for the support!
The bike is being appraised. My helmet, mirror, and glasses are absolute toast. There's a scary huge section of the helmet missing, and the paramedics outright stated that had I not been wearing it, I would be brain damaged or dead right now.
I will be retaining a lawyer in order to make sure I do everything properly and am well defended in case the offender decides they do not want to pay for the damage they have caused.
I truly wish I could write more about this but it is not in my legal interests to do so at the moment.
