Another reason for SRF to be gone forever:

There's an exploit in GT6 Quick Match races where if you have SRF enabled in an offline race, it will stay on for an online race, even though the rules specifically disables SRF. There's no way of telling who has it on or off, so pretty much you have to use it, or be resigned to languishing in the midfield while other people flies past on the outside with no loss of grip whatsoever 👎
GTS not having SRF that means we can guarantee that everyone has a level playing field and driving with the same physics. If a guy is faster, he's faster. Period. No need to suspect they are using a hack or cheating.
Until PD mucks up something else that is. I wouldn't put it past them...
