This is just like people want to do a warm-up lap before the start of a race. I own a game in which you can do that, but in fact it is so boring, that i always skip it.
Same for driving in your pitbox in GP4. In the end it's just boring to wait till your car is inside before you can do anything.
So i am pretty happy that GP3 does not have this option, but just a quick stop and go is possible.
Ibanez guitars played by people like Joe Satriani and Steve Vai make me wanna go fast!!
