If you make 3 extra PSN accounts & add them to your main one, then you can farm credits by running races from your main account, using 5 drivers from each of your other accounts.
I think he might be referring to this topic. You may need to read though the entire topic for details. https://www.gtplanet.net/forum/showthread.php?t=200544Sorry for bumping this but really, that doesn't make sense. You can't create more than one driver on a new account if your B-Spec level is 0, actually you need to go up to 25 until you can create all 6 drivers. And if you host the races from your main account you can only use one of your drivers, while you can use all of them if you host them from another account.
