Pretty much all drivers are subject to the risks mentioned above, so the short answer to the question is, "Almost everybody." Take animal collisions, for example. According to the Insurance Institute for Highway Safety, there are more than 1.5 million deer-vehicle collisions every year, resulting in over $1 billion in vehicle damage — and that's just deer-vehicle collisions.
Comprehensive insurance is a coverage that helps pay to replace or repair your vehicle if it's stolen or damaged in an incident that's not a collision. Comprehensive typically covers damage from fire, vandalism or falling objects (like a tree or hail). If you're financing or leasing your car, your lender likely requires comprehensive coverage. If you own your vehicle outright, it's an optional coverage on your car insurance policy.
