I think with F cars, the issue is not just the lack of low down torque, it's the gearbox's insistance on getting into 8th by the time you are doing 6mph (slight exaggeration). Obviosuly this is done for fuel efficiency, but it's PITA when you want to make effortless progress.
Yes, you can stick the box in to manual, but let's not forget that the IS-F, RC-F & GS-F are not balls out sports cars and are arguably every day cars.
