I was just talking about this with my son yesterday. I rented a car for 5 days last week to go to Lake Louise. I used my credit card to pay and that provides insurance for car rental. So I paid $280 vs $500+ if I took their insurance.

I think this is a scandal and a rip-off. Something should be done about it.

Same when I rented a car in Scotland a couple of years ago. With credit card (ins included) about $600 for two weeks. Rental company's collision (etc) insurance would have cost at least $1,200.

How many people are the rental companies ripping-off with this situation, I wonder.
