Most cars are still steel. Source I work on cars in New England. So much rust, even on the ones with aluminum bodies, at least wherever it can touch a dissimilar metal and becomes a battery.
And crucially the important parts that keep it from exploding (cylinder liners) and save you in a crash (crumple and bumper cores) are almost all steel. Because it deforms better with simpler engineering.
