You expect your car insurance rates to increase after you buy a new vehicle, cause a crash or add a young driver to your policy. But some insurers jack up prices based on seemingly unrelated data — like your magazine subscriptions or what groceries you buy.
Even if you have a clean driving record and have stayed loyal to your insurance company for the past 10 years, you could be paying higher premiums than someone with the same driving history, car and background. Why? Price optimization.
