2. If there is any amount that the car rental LDW does not cover, the credit card will take care the rest.
Can you cite even one credit card whose rental-car coverage terms and conditions state that purchasing optional, partial-LDW coverage from a rental-car company will not void the card's coverage? I'm not saying that no such card exists, but I've never heard of a credit card whose coverage would still apply if a cardholder were to purchase optional LDW coverage from the rental-car company.
