I've been told that most rally cars retain their standard transmission even if installed with a sequential flappy paddle gear box. Thus allows them to keep driving if the hydraulics in the sequential fail. Also skipping gears is faster in the standard so if the car spins out it's easier to get to first. I didn't see it in the video but I suspect his shifter is right there under his enormous e-brake. Please correct me if I'm wrong.
