But I think it’s hard to generalize as there are many safety factors and there are some cars that are safer than some SUVs (I survived a Chevy avalanche t-boning my Saab 9-3 that totaled both cars and had both avalanche driver and passenger taken away in stretchers and I took a cab home).
But, generally speaking, SUVs are safer because they have such greater mass. And SUVs also have safety features.
