Are they really? A quick search for "US pedestrian deaths by vehicle type" and I came across this 2005 study [0] looking at pedestrian fatalities per mile by vehicle type (and I'll admit some has changed in the nearly 20 years since the study was published). What surprised me was motorcycles caused more pedestrian fatalities than light trucks per billion miles. Urban buses had the highest kill rate, nearly 4 times that as light trucks.
Happen to have anything with more current statics?
