A couple of issues separate car insurance with home insurance. You can still buy a car and drive it without insurance, albeit illegally in most states. With a home you cannot even BUY the home (with a mortgage) without home owners insurance. You could "self-insure" but no lender will give you a mortgage without insurance. Whereas a car dealer will gladly sell you a car with or without insurance.
Eventually, government will mandate insurance before buying the car.
