Both you and the driver of the vehicle you hit are fortunate in that an ambulance scoops you up quickly and gets you to a nearby ER where you're both stabilized for the time being. You're doing okay, but the other driver is in bad shape. He needs a kidney and some blood. Miraculously, you're a perfect match for both.
You have a terribly hard decision. You're stable at the moment, but this seems like a risky time for you to undergo a surgery to remove a kidney, even though the victim in the accident you caused will not live without the transplant. Even donating some of your blood to him jeopardizes your likelihood of survival.
Ultimately, you make the call that you can't bring yourself to do either thing. There are many reasons that you use to justify your decision, but none of that matters--it's your call and only your call. The family of your victim goes from begging to threatening lawsuits, but there's nothing they can do. Your right to bodily autonomy is absolute. No court can compel you to use any part of your body to save the life of another person for any reason.
The family of your victim rallies almost immediately. Surely, now that you've passed, they can get your life-saving kidney. In this case, your death changes nothing--you weren't a registered organ donor and your family is inclined to honor your implied wishes. Your organs die with you. Even in death, your bodily autonomy is unassailable.
