sounds like something I've gone through before. 50/50 means you are both equally at fault, therefore it cancels out any reason the other party would have to pay for your damage. if it were the other way around i'm sure you or your insurance wouldn't want to pay up either.
by no means am i defending the insurance companies and their policies, but I've had enough experience with them to know how they operate and sadly, it really isn't ever in our favor.
get a truck or suv, and the little cars won't stand a chance
