Speaking as a former P&C agent for Progressive, as well as doing customer service for them, and then claims for a different company, it’s rarely arbitrary, but often unfair in the personal sense.
Like when a carrier raises rates 4-8% nationwide, to subsidize losses in high-risk areas, like Florida, or New Orleans. But if/when they exit those markets, they never seem to drop rates to allow for that reduction in exposure. The worst of both worlds.

But insurance is about the laws of large numbers and it means a lot of very good drivers are paying higher rates to cover the uninsured, underinsured, and just bad drivers out there.
So, given the costs of repair and parts have skyrocketed, the sheer number of propriety parts and repairs out there, it can be drastically unfair to individuals and that’s before we ever consider the profit seeking nature of most carriers these days.
When you would go to an agent, before my time as it were, you might get a pamphlet, a sticker, or other minor mention. When I was a child, advertising was often just a subdued commercial on local TV or “Mutual of Omaha’s Wild Kingdom”.
Now everyday when I’m streaming something with commercials, I’m bombarded with loud, sophisticated (and not) commercials blaring out how great this or that carrier is every 20 minutes, with 2-4 different commercials in rotation.
So you’re paying for them trying to convert everyone ELSE, not just cover you. And still, despite those additions, rates don’t seem to go down.
And even knowing better, I’ve been burned on the whole thing. I have had my Homeowner’s carrier for almost 20 years now, and after the first year or two, hadn’t been careful to check how they were amending my coverage while raising my rates slowly but steadily. Until I made my first (!) claim in 20 years for a roof, and they nickeled and dimed me on every tiny exception, and created truly one in a million reasons why this or that damage came from something uncovered.
Well, new roof will be finished Monday, though the battle on the siding continues. Once it’s all done, so are they. If you don’t care for how you are treated, the ONLY thing they notice is bad publicity (and it has to be REALLY bad) and churn. So give 'em the churn.
