So best case for someone like this: don’t drive. Get other people to drive you, use public transportation, get a bike, etc. But this is probably America and that is 100% not possible everywhere. Or even most places.
There is another option: State-Owned High-Risk Auto Insurance. These are insurance plans owned by individual states. Because US states all require auto insurance to drive a car and because driving a car is goddamn necessary in a lot of America, this exists.
It’s VERY expensive. Like when I was looking at getting good coverage for 2 newish cars I was staring down $500/6mo. Our state’s high-risk was $2,000+. But it exists for people like in the post who are just too expensive for ordinary insurance companies to want to insure.
