Other studies indicate a much higher difference in mortality rates:
"The average risk of death for a pedestrian reaches 10% at an impact speed of 23 mph, 25% at 32 mph, 50% at 42 mph, 75% at 50 mph, and 90% at 58 mph"
Interesting, fair shake on that. But my point about proving things beyond a reasonable doubt in a criminal prosecution still stands.
Also I haven’t read up on West Virginia statutes on this, but many places the law is written such that for a vehicular homicide or involuntary manslaughter prosecution to happen in a situation like this, the conduct on the driver’s part has to go beyond mere ordinary rule-breaking. That it has to constitute recklessness or at least gross negligence. I just don’t think that the way a jury will think about it, that driving (maybe as little as) 47 mph in a 35 zone, or even (as much as) 55 in a 35 really reaches that bar.
New York State prosecutors used to follow this extremely frustrating “Rule of Two” notion where they wouldn’t even consider something like a vehicular manslaughter charge unless the driver was breaking at least two laws with his or her driving, mere speeding didn’t pass muster.
Personally I wouldn’t like to see people thrown in jail for crashes like this, but I would like to see an extremely muscular culture of permanently revoking people’s driving privileges in the event of an injurious or deadly crash. That the law should just have a strongly built-in belief that the driver has the strongest responsibility for road safety and should be presumed to be at fault in the case of a victimized vulnerable road user unless there is tremendous exculpatory evidence to the contrary.
This is how the Dutch handle this and it works well. Same presumption of responsibility in Japan, again, much much safer road culture there.
But at least in 2023 in the United States we’re not there yet.
From @Scientist :
Depending on how far away he was when he saw her and started braking, the difference in driving speeds (55 vs. 35) could have been the difference between the driver still going 30 mph or having come to a complete stop by the time he reached the girl.
Oh, 100% agree. Though if a person steps right in front of a moving car (or, um, me, on a bike) close enough to its arrival there’s possibly no speed that would have been slow enough to prevent a collision.
