You'll probably never get out of second gear at an autocross, so it would be as pointless as the button - almost. Just giving you a hard time. It's just the same as an extra gear to shift into and hold the car in that gear, except it's a button. And you cannot force the car to shift into third, you have to wait until it decides to do so - or runs out of second gear. But you can stop it from going into fourth!
