100% of the peer reviewed science* on the subject says you're a fucking idiot. Are you claiming (and do you actually believe) that larger vehicles do not, or cannot, have crumple zones and structural strength equal to or better than smaller vehicles? Is there something about a larger vehicle that makes it inherent that the driver will somehow be at the front, where in a smaller vehicle they would not, despite there being a lot more room behind "in the front" in a larger vehicle? There's nothing about a larger vehicle that prevents such safety features from performing at least as well as in smaller vehicles.
None of this is new or arcane research. It's been well studied for decades, and well publicized.
Were you born this stupid, or did you take lessons?
*" In car crashes, other vehicle parameters with statistical significance had a second order effect compared to mass. In light truck-to-car crashes, “vehicle type-striking vehicle is light truck” was the most important parameter after mass, followed by vehicle height and bumper height, with second order effect"
(Note that big SUVs are also taller that shoeboxes, another way they're safer in a crash.)
*"As in Phase 1, mass was the most important vehicle parameter, contributing approximately 20–30% to the variation in fatality odds in car crashes."
