Eh? I deal with motor insurance, and hire fairly frequently.
CDW is essentially, you paying to reduce the excess. IE the car might have a £500 excess. Paying say £5 per day extra, usually reduces that down to nil. I don’t see what the insurable risk is here? Unless the CDW is only removing the excess down to say £200? Even then, seems a rip off to me.
In the UK for example your insurance has say a £300 excess. You have a non fault accident, and you get put into a hire car. The TP part of your insurance transfers over from your own policy. But if the hire car has a £500 excess, then you might elect to pay CDW. But if say, your own excess was £300, and the hire car has a £300 excess, then whatever happens, theres a £300 excess. Olny one excess can be decducted, as the claim is only made on one policy. So insurers refuse to refund CDW, as to pay it gives you betterment. IE the hire car then has a policy on more favourable terms than the policy you actually chose on your own car.
So that website links to an example of a £2000 excess, and this policy is essentially insuring against that. But what sort of hire car firm runs the risk of trying to recover £2k from any driver, especially in the tourist market, when people disapear abroad after their holiday ect. I have never seen an excess that high? The ad even mentions declining the care hire excess insurance, yet it may be less than this? Bizarre.
