Probably because in a real racing seat there’s a harness to keep you from slouching. I used to have terrible lower back issues with a Recaro bucket seat I converted for a desk chair. Never had a problem with it driving for hours when it was in my car (may it rest in pieces). Then it dawned on me that the seatbelt was maintaining my posture. Added a lap belt and the back problems abated.
