At first, I was going to criticize the collision speed of the example study, but found ( ok, I say found, I mean I googled for 15 seconds ) that the average American collision is occurring at less than 40mph, so good to go there.
Second, I was going to comment on the relative safety of being in the Kei truck and being struck by the 2500HD... but that just goes back to the 'participating in the arms race', so feels... stupid.
So, overall: Thanks for providing this. It directly answers the primary concern of 'what if I hit something tho'. There are some other angles I could nitpick on maybe, but they all feel like a kind of 'consolation prize' to the argument.
