Again.... the statistics prove you wrong.
Motor insurance is so competitive that if an insurer could really get away without loading premiums for non-fault claims someone would have done so - and everyone else would have to follow suit. The fact that premiums are loaded is in itself evidence that people who have made non-fault claims are more expensive as a class.
Look up anti-selection if you don't believe me.
Apologies to all if this is drifting off topic, it's a subject I find academically interesting and enjoy the debate. I can see your point regarding anti-selection, but I'm not sure that's how the customer perceives it, leading to the bad feelings described above.
I can see no intuitive reason why the following analysis is incorrect (illustrative example and figures used):
- I am in my car and rear-ended via a four vehicle shunt. The car behind me broke late, thus causing the bus two vehicles back to commence the shunt
- I assess the damage to both my vehicle and myself
- I conclude that the cost of repairs would be £300
- the excess on my insurance policy is £250, therefore all else being equal I would have some interest in making a claim
- I determine that by making a claim I would possibly lose my no-claims bonus of 8 years (if not protected), and I would have increased premia in any event, which would have a total net present value cost to me of at least £500
- I therefore choose not to claim and my cost of insurance remains unchanged
Why am I at any higher risk of the same scenario occurring a week later? I am not - hence I the risk associated with insuring me is no different. When I initially said "claim", I think you are correct. If someone has a propensity to claim, then indeed they should be charged higher premia. But in this limited example, it has no link to their actual risk as a driver. But when an insurance company increases someone's premium, the customer assumes they are being described as higher risk. They are not, they are being assessed as a more expensive customer. Which comes back to the earlier point made that insurance companies do not do a good job of explaining their pricing, which in turn generates anti-insurance company feeling (particularly as it is a legal requirement, which forces people to be subject to the impact of anti-selection).
Having a no-fault accident tells us nothing about someone's likelihood of being involved in a further no-fault accident. But an insurance company's pricing indicates otherwise.
