>Sedan hits you, you get hit in the knees and fall on the hood. Brodozer hits you, it strikes your chest/head, pushes you over and drives over you.

You just made that up. Pedestrians are mostly killed by head onto solid object.

Your two most common options are pavement and windshield. Pavement is worse because cars have a fair bit of engineering that goes into preventing head onto windshield. At the end of the day it's mostly a question about getting hit above or below center of mass.

Modern (ie. larger than they were 20yr ago) crossovers and midsize SUVs are doing a lot of heavy lifting in these stats. But the people who want to talk about this problem tend to drive Rav4s and not Chevy 2500s so the latter gets complained about even though the former outsold it 2:1

Relatedly, minivans are kind of bad no matter how you cut them because it's hard to stay true to the form factor and not have pedestrians go straight into windshield in fairly low speed crashes.
