>> negligent homicide (although it's usually treated as manslaughter instead of murder)
Not usually. It can never be treated as murder. If it was negligent then the killing lacked indent per se.
>> If you are unable, or unwilling, to handle a loaded weapon with the requisite amount of care to avoid negligence
Good luck selling that to the AARP. People have medical incidents behind the wheel every day. A heart attack/stroke/seizure can easily result in a crash, including deaths. We don't lock people up for that unless they were negligent, unless they had some reason to know it would happen. Everyone one of us may suffer an aortic dissection or brain aneurysm at any moment. That's why large commercial aircraft have two pilots. Driving while human is not negligence.
Criminal negligence applies when you could and should have taken steps to prevent the incident but failed to do so. Having a heart attack while driving is not negligence, unless you are somebody who has a medical condition that makes a random heart attack while driving a likely foreseeable outcome (say, angina).
That said, many car crashes are probably caused by negligent actions anyways. Someone who is speeding through a stop sign without stopping is negligent in doing so, especially because the kind of people who do that once tend to do it all the time.
To further your position and to loop it back to the original point about crash vs accident: even in the case of an AARP member who had a heart attack that leads to a collision, accident is not the right word. There is nothing accidental about it. We know that building infrastructure that requires driving into old age will result in deadly collisions, yet we continue to choose to invest to grow this infrastructure. The resulting incident is a crash or collision, not an accident. A good book on the subject is Normal Accidents by Charles Perrow.
