I'm considering getting the CSP where the primary auto rental coverage is a large reason I would hold the card. The linked terms and conditions say I would need to put the entire charge on the CSP and decline the rental company's insurance.
I searched but I can't find any discussion of using a rental company's points to offset the rental costs. The prior discussion of using UR points and not having primary coverage makes sense, you haven't put the entire charge on the CSP. But by using Hertz points for example, it shows on the receipt as using a coupon and the full amount of taxes and fees are put on the card.
I typically use Hertz points I earn for personal trips since they usually have a decent value, and if the CSP wouldn't provide protection for points rentals that really affects the math in keeping it long term.
