I'm sorry, guys. I just have trouble figuring out what to do in the game, even with the advice.
Also, I did more than 36 laps around Grand Valley and that took a lot more than ten minutes and I was only able to get my qualifying time down to 1:48.494 even with all those laps. I need to master rolling the joystick along the rim to steer and go fast with a controller, don't I? Traditional simple left or right joystick movement is sadly still severely ineffective. A substitute for trail braking would also be nice.
If those can't work, then I guess I'm just not the champion I want to be and champion controller users like Calster are still very rare even with so many updates. I'm sorry for complaining and giving the impression that I was trolling. I'm thinking about getting a good steering wheel someday. Using a controller in Gran Turismo 7 really does make me feel handicapped.
