This is already known. Giant SUVs are more prone to rollovers and then crushing themselves and their occupants. Mid-sized and large sedans are far safer for 2 reasons: 1. structurally, they have smaller forces to contend with over a smaller surface area which makes building a safer passenger cage area easier and 2. American safety regulations for cars are more stringent than those for SUVs and pickup trucks. Instead, it's a Cambrian explosion where megafauna race to be the largest thing on the road, and screw everyone else and fuel/battery economy.
