'He's old enough to know better': Entitled brother demands sibling chauffeur him indefinitely following $18,870 fine for driving uninsured

An $18,870 fine after a traffic stop is absolutely insane. Unfortunately, this is the harsh reality for the OP's 26-year-old brother, who now has one year to pay it off. Working extra hours seems like the obvious solution to generate the needed cash. However, this assumes the OP hasn't had to sell his car to cover some of the expenses. Regardless, his license is now suspended, meaning the entitled brother relies on others for transportation.

The OP is seeking advice from the Internet to determine if he's justified in refusing to drive his brother around. His stance is rooted in the belief that if you commit the crime, you should face the consequences. However, the OP's family doesn't share the same perspective. What course of action would you take in this situation?
