This paper seems to not have controlled for vehicle weight, which is the most obvious thing I could possibly think of being a confounding variable (specifically, total force applied). They specifically call out the variables they controlled for on pages 9 & 10 of the paper (https://www.iihs.org/topics/bibliography/ref/2294). |
