When you kill yourself because of a predictable risk it's on you. When you kill someone else because of a predictable risk that should qualify as negligent homicide, at least (and lower-risk things than driving do).
Okay, that applies to pedestrian deaths. But the vast majority of driving deaths are based on mutual choice to drive. As long as nobody's drunk it's rarely a 'kill someone else' situation, rather it's a 'two drivers interacted in a way that went wrong' situation.
Negligent homicide should not apply if the negligence was mutual.
