Comprehensive car insurance covers damages from an "act of God," or events that are not caused by a car driving into something else. An "act of God" can include things like damage from a heavy tree branch falling on your car. Since you have no control over when or why a tree branch would fall on your car, this kind of accident would be covered under your comprehensive policy.
Auto insurance is financial protection, and not just for the investment you made when you bought your car. After a really serious accident, bills for damage and injuries can easily reach into hundreds of thousands of dollars. If you happen to cause such a wreck, the victims could sue you. In the worst case scenario, assets such as your savings and home could be seized.
Location: Insurance companies have to pay out if your car is stolen so they will take into consideration where your vehicle sits every night. “Insurance companies are constantly looking at data to justify rates. Where you live can definitely have an impact on rates if there is a higher incidence of theft or vandalism near your home compared with other areas of town. Urban areas usually have a higher rate of accidents and theft than rural areas, so rates are higher,” says Biggert. “Each geographic area has its own set of risks, and the insurance carriers know what they are and how often they occur.”
