Exactly! You are not forced to buy car insurance because you are not legally required to drive. Car insurance is a necessity only if you CHOOSE to drive a vehicle. Not only that but you don't need car insurance to have a driver's license. Car insurance is required by the lien holder as insurance against losses incurred.
Florida is a no-fault state, and you can drive a car without insurance if the vehicle is title-owned by you. Personally, I prefer not to do that, I carry insurance on all of our title-owned cars, but not because someone TELLS me to.
