The change in technique on the transition from pavement to dirt sections is incredible! Short shifting, skipped shifts going up through the gear box, counter-steering (seemingly to the limits of lock to lock)...and dodging spectators from time to time. Excellent video. The shifter is called a sequential box (like a motorcycle transmission) and the computer probably does the rev-matching on the down shifts. Push forward for down shift, pull backward for up shift; no gate to negotiate.
When I see a driver with that level of talent, I reassess my own abilities...downward
