I'm sorry to hear about your accident.
I agree, drivers just don't register anything with two wheels in their brains!!! If you don't have two head lights & a bumper, you can't hurt them & therefore, you don't matter.
I've been in two serious MC wrecks & both times my helmet saved my nugget. I was riding MB's for a few years without a helmet, but we wear 'em now.
Get well soon!
