Why double clutching and not granny shifting?
BECAUSE RACE CAR
“You almost had me? You never had me. You never even had your car. Granny shifting not double clutching like you should.” – Dom Toretto, The Fast and the Furious
PS Dom - Double-clutching is primarily used by road racers that need to match their transmission speed to the engine speed while downshifting through turns. Drag racing is in a straight line, and you shouldn’t be double clutching or downshifting in the first place, as there are no turns involved. So technically, you’re both idiots.
