Rental cars in Mexico don't come with legally required liability insurance, and your own liability insurance from USA doesn't count. Your credit card doesn't offer liability insurance, just collision and damage protection. I don't know if they tried to explain this to you and failed, but at the end I guess they just let you drive without legally mandated insurance and take the risk. I personally wouldn't take that risk in Mexico (or any other foreign country).
