I don't believe you. This description of benefits for any visa signature card says:
Within your country of residence, Visa Signature Auto Rental CDW supplements, and applies excess of, any valid and collectible insurance or reimbursement from any source. It does not duplicate insurance provided by or purchased through the auto rental company; it will not pay for losses reimbursed by your own insurer, employer, employer’s insurance, or any other valid and collectible insurance; however, it will pay for the outstanding deductible portion or other charges, including valid administration and loss-of-use charges not covered by your applicable automobile insurance policy. Outside your country of residence or if you do not have automobile insurance, this benefit is primary in those countries where it is available, and in that case, you do not have to claim payment from any other source of insurance before receiving the benefits.

Of course, you have to refer to the actual agreement for your card to know for sure, but I believe that most credit card rental insurance applies to people without car insurance.
