Most credit cards that do offer it only offer it as secondary coverage. I.e., it'll first hit any personal car insurance coverage you have, and in that case the card will cover the deductible. For ones that provide primary coverage, Amex's premium coverage is very good, and will run you ~$25 per rental period (not day, period, up to 42 days), but you have to call (once) to get it added to the card. It doesn't include liability or uninsured motorists, but for just "hey, something happened, the car got damaged, but I don't want to be able to just walk away and not worry about it", it's an easy, braindead option.
