> Cars kill 40k+ people in the US each year, and speed (really momentum) is a large factor in the lethality of crashes. But what actually causes crashes? Speed alone does not cause crashes It's reckless driving, distracted driving, poor driver training, drunk or otherwise inebriated driving, poor road design, drivers suffering medical emergencies behind the wheel, etc Why so much focus on fixing speeding and so little on training people to be better and more responsible drivers? Or removing terrible drivers from the road?
