I have questions about the pedestrian article. The article states that almost 3/4 of all vehicles sold are light truck or SUV. So wouldn't it just be statistically more likely that for ANY accident it would be a taller vehicle?
The actual paper discussed in that article isn't just comparing frequencies of accidents, but rather using them to calculate the odds that a given vehicle type causes a pedestrian accident in a variety of scenarios. In doing so the author determined that these vehicles were overinvolved in accidents relative to their frequency on the road.
