Don't know if the US is the same but with UK Zipcar over 21's can pay a small amount (£15/month or £99/year) to reduce the damage fee waiver to £0. That way there's no liability except if you use the car for things that Zipcar prohibit. We do this for each rental after being stung for damage done to the vehicle after we'd returned it[1]. It's an annoying flaw in their rental model; I now take photos/video of the car after I've returned it to hopefully prevent getting the blame in a future similar scenario. 1. You're essentially liable for any damage up until the time that it is next booked out. We had to pay as there was nothing we could do to prove it wasn't us. That damage even includes things like "damage caused by unavoidable events such as floods, hail, wind, trees falling, etc."
