I sometimes notice this until I get up to speed in an unfamiliar car.
But something that I find really helps the AI pay more genuine attention to me is changing the aggression right down, to 10 or less, and then in plr file I change these (original figures in brackets):
AI Brake_Power Usage="0.95000" // ("0.99800") // Fraction of theoretical brake power that AI attempt to use (can be overrode in HDV)
AI Brake_Grip Usage="0.95000" // (0.99000") // Fraction of theoretical brake grip that AI attempt to use (can be overrode in HDV)
AI Corner_Grip Usage="0.98000" // ("0.99000") // Fraction of theoretical cornering grip that AI attempt to use (can be overrode in HDV)
Ok, I know a lot of people argue that it reduces the aggression too much, and for tintops they may be right, but for formula 1 cars, where non-contact is the norm, I find it really improves their behaviour into turns.
