The catastrophic situation you are insuring against isn't repairing your car, it's your liability for the property and people you hurt in an accident. Unless you're with one of those state minimum insurers, you're probably insured to pay out somewhere between $100,000 and $500,000 to whoever you injured. You wouldn't expect the $N per month for this coverage to change that much whether your maximum payout is $510,000 or $505,000. All the other things that went into deciding your premium (location, accident history, etc) don't automatically change year over year.
