Minimal Cars. Maximum Shiekras, er, Shrieks.

North America's first diving coaster, SheiKra at Busch Gardens Africa in Tampa, Florida takes riders to the precipice in a single 24-passenger, precariously open "floorless" car, dangles them for a few heart-skipping seconds, then drops them straight down a 200-foot hill. And that's only the beginning of this wild ride. Read my review of SheiKra, one of my top picks for parkdom's best steel coasters.
