Track & Layout Used: Any Car Used: Any Applicable Settings: Enable "authentic" or "off" in the gameplay's authenticity sub-menu Report: SC, TC, and ABS were STUCK ON, even though I forced them OFF since day 1 in my Menu settings. While I did not assign these functions to my keyboard or steering wheel in order to cycle them while on a lap as @John Hargreaves has done, I did follow @NuScorpii advice and cycled them through and re-saved my settings a few times - This bit of fiddling did absolutely seem to get rid of the driver aid/stability issues mentioned. Steps to reproduce: Launch any car/track with "authentic" assists on or all assists "off", drive laps. Exit and cycle through the assists off/on again. Re-try on same track with same car and see if assists have switched off finally.
