In short, the MCCA pays for medical benefits from very serious auto injuries, those that go over $500k. Everyone with a car in Michigan pays into the fund. But, the fund's bookkeeping is secret. Now the MCAA is saying they don't have the money to continue to pay, but that no one needs to see their books, because we wouldn't understand them.
Although all insured auto-owners pay into the MCCA fund, the public is not privy to the assumptions made to determine the fee they pay each year. The insurance executives decide the amount and by law auto-owners pay it.
To me, this is insane. If you get public money to create a fund, the funds books should be public knowledge.
