Unless you’re talking about the rear single piston brakes on some smaller cars I can’t think of one car that doesn’t have more than one piston calipers. I’ve never heard of one with less than two on the front.

My 2006 STI had 4 pistons in the front. This isn’t necessarily new tech.

Brian earl spilner? Sounds like a serial killer.

This dudes a cop!
