Yeah, this just seems to be one of those rather unhelpful things that AC does. Once you get used to it, you'll remember to fix it each time. If I recall correctly, there's also a warning shown (very briefly!) each time you exit the controls settings page.When I play with the Options - Controls settings (gain, effects etc), then go back to Drive, my Realism settings have changed - Automatic Clutch and Automatic Throttle Blip are turned off. The other settings are not affected.
