Excuse me I had to recheck the CDC data, the most common spots are actually in urban areas on shoulders or where there is no crosswalk. Basically in places where pedestrian infrastructure is poor.
Do you have a link to this data? I'd be curious to see it.
I've driven through/around the deadliest city for pedestrians and in my experience driving there, it seemed both drivers and pedestrians had a death wish. Many drivers were running red lights and many pedestrians were just crossing wherever they felt like it. Also, lots of people obviously on drugs vaguely aware of their surroundings.
So what you're saying checks out, I'm just wondering about the degree to which these things are a factor.
