Arizona recognizes an approved refresher course
Drivers over a qualifying age who complete an approved mature driver course are entitled to a premium reduction from insurers for a period afterwards. It is a genuine statutory benefit, the course is short, and a great many eligible drivers have never been told about it.
Retirement changes the mileage profile
A household that stopped commuting is driving substantially less than the figure on a policy written during working years. Mileage is rated, the old number persists until someone changes it, and nobody audits it in your favor.
Loyalty is not reliably rewarded
A policy held with one carrier for twenty years is not automatically the best priced. Rating methods change and long-held policies frequently sit on older ones. Shopping it occasionally is not disloyalty, it is the only way to find out.
