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.
It’s relative mass that matters. Weight of a car to the weight of a person is so high that a vehicle being 5 times heavier than another vehicle is irrelevant.
Like I said above, a high school physics student knows better than this.
Show us your math so we can laugh at you.
You sound like someone who has learned to critique scientific papers, but hasn’t learned enough about how to actually improve on their methods. You sound like an absolute dick.
The paper shows vehicle height contributing to more serious outcomes. You could infer that the weight of the vehicle is correlates with vehicle height and therefore the mass of the collision is incorporated in the data. Vehicle height has the added benefit of also incorporating collision strength as pedestrians can’t fall on the hood of the car and have that absorb some of the impact. There are huge vehicles that will probably hit me right in the head on a collision which would further contribute to the severity of the impact.
You sound like someone who lacks the reading comprehension to perceive that I differentiated the underlying science from the article’s presentation. So, you resorted to ad hominem while explaining vehicle physics to someone with a mechanical engineering degree with automotive specialty.
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.
