>those are thousands of ostensibly independent events that don't necessarily have a single common cause
This is obviously incorrect reasoning for the United States. If countries around the world had statistically similar collision rates, then you would have a point, but this isn't some sort of power law or random distribution. The fact that our fatality rate are so significantly higher than other developed countries, means that there is a reason. It's not random, it's statistically showing us we're doing something very, very wrong
Is it possible the US just has more bigger vehicles? Speed is obviously a huge part, but adding all that extra mass of many super-size me trucks and SUVs with poor visibility seems like it would factor in.
If you’ve studied the subject, the obvious reason is that Americans allow anyone to drive with minimal training. Regardless of past behavior. We even subsidize insurance rates for people who are so bad at driving they are uninsurable.
