IIHS researchers analyzed pedestrian crashes to develop injury risk curves showing how speed affects crash outcomes. They found that the effect of crash speed on injury risk was magnified for vehicles with taller front ends. Compared with risk curves developed using crash data from Europe, where tall passenger vehicles are less common, risk curves for the U.S. show pedestrians here begin to suffer more serious injuries at lower speeds.
You’re not talking science, you’re being nitpicky, condescending, and pedantic.
You can talk science when you bring out the math, demonstrating the scale of differences of vehicle weight on the acceleration of a pedestrian, or when you have published your own safety study.
