I am in Florida and my policy covers incidental driving of my car by other licensed people who are not related to me. But when my daughter got a license (we had 3 cars and 3 drivers and she made it 3 cars and 4 drivers) the cost almost doubled.

If you are not driving the car the license is not going to affect the insurance, and yes the car would still be covered if you had to drive your roommate to the hospital or go get him because he was drunk or whatever, you don’t need to be on the policy.

Car insurance is SO expensive here partly because there is no public transportation so everyone and their Grandma is on the road crashing into each other. Another example of trying to save on social cost but increasing everyone’s cost and risk so it ends up costing more not less.
