Are some cars impossible to drive well with the mouse, or does it just take time? The XRG seems to slide everywhere and I can't keep it in control. I've gotten better with the FBM now but I can still slide out quite easily. I had a go of the BMW sauber at a friends and that just seemed impossible to drive. I've tried various setups for the FBM etc but half of them just seem to make it slide even easier.
