The guy yelling is called the co-pilot. Their job is to know what turns, speeds, and terrain is coming up to convey to the pilot/driver. They’re going so fast that they literally don’t know what’s coming up or how to take the corners, so they depend almost entirely on their copilot to tell them about what turns and what speed they should be at before the turn and then they convert that into really badass Rally powersliding action.
This is rally driving.
