Man I would be livid.
I had some asshat demolish my rear end and then try and weasel out of paying for it. I was NOT going to claim the deductible so I filed a "mini-tort", in MI you can do this as well as other no fault states. It's a legal doc that lets you sue the other person for the damages. I did this through advice of my insurnce company and I never paid a freakin' cent!
