I never ran at 300kmh in a heavy and high frequency bumpy surface, but i am not so sure the human eye is designed for a static view in such extreme conditions, furthermore the subject of eye behaviour looks in this thread a personal experience and perception
I agree with you in real life your brain, inner ear etc etc to things to compensate for all this I agree, but honestly after having raced tons of laps in FF1600 and FF2000 and a limited test of an open cockpit prototype car trust me in saying that if you want the most realistic experience, if your training for real life and need to prepare yourself to the SUPER VISCERAL experience of this stuff, then I would keep it on, or just slightly decrease it.I was only pointing about the rough surface and the extreme conditions of the banked turns at Monza.I've experienced plenty of g-forces on track and as a flight test mechanic. In either case your head does not "bobble" all over the place.
Please get someone to take you out on a race track sometime to experience it for yourselves. There is no wild shaking up and down.'
