Auto insurance required by law is to protect others not your self. Once you own the car all the insurance you need to meet legal requirements is liability. The lender requires insurance to protect them while you have a loan. The state requires insurance to cover damage or injury to others.
All states I know about allow you opt out of insurance if post a bond or can some how show you can cover injuries to others with out insurance.

Then you shouldn’t have a problem paying health insurance for others.
