Just curious.....did the person who hit him not have insurance? They should be responsible for his medical bills if they had insurance.
If the accident was his fault and he was still paying for the Mini Cooper then he should have been required to carry full coverage insurance which usually includes medical.
If he was driving with no insurance then he has himself to thank for his "problem."
Regardless of fault, auto insurance does not help you in the short term. Without health insurance, you are responsible for all medical bills until the claim is fully settled and you can’t settle until everything is finalized or you’re screwed. It’s a catch-22 that I would not wish on anyone.
