Good point -- there's a 4% chance of fatality when struck by a 15mph car versus 20% at 30mph. There's a 30mph city street near me where cars routinely go 45mph

Good point -- there's a 4% chance of fatality when struck by a 15mph car versus 20% at 30mph. There's a 30mph city street near me where cars routinely go 45mph -- the fatality rate jumps up to 60% at that speed. So just having cars follow the speed limit would go a long way toward reducing fatalities. https://www.propublica.org/article/unsafe-at-many-speeds https://www.propublica.org/article/unsafe-at-many-speeds
