So little respect for people's stuff....

insurance is nothing more than betting against yourself.My feeling is that carrying anything other than liability is a scam .If you calculate what you will spend over your lifetime on all that other non essential insurance like collision and such as opposed to what it will cost you to just pay for things when they get screwed up you are probably spending way more on insurance than cost of repair
On average, if you take all the people paying for insurance that they do not use, this does work out. That's how the insurance companies make money. But if you are the guy that has to shell out $30-$40K for a new car, well, it doesn't work out for you!
