We've been asked that question before on security questionnaires, and our answer has always been, "Forcing users to change passwords regularly is widely regarded as a very bad security practice, and we don't engage in bad security practices." We've never had anyone complain.
I've never had a complaint about anything I put in to a form requesting a quote for insurance. I just get the quote back. Did you write that in the comment expecting an insurance salesperson to call you up and argue passwords with you? Call their back office and say "hey this guy says our password question is crap, get our best guys on it!"?
I just cant imagine any outcome other than it was translated to just a "no" and increased your premium over what it would have otherwise been.
I've also filled out insurance quote forms several times to see the interplay of the questions and price. Quite often many of the questions do not change the quote. So the existence of the question in a form does not imply a change in price, or any true guess at the magnitude of the change at all.
