How exactly? If you lose the rear end in a FWD car then it's generally lift-off oversteer. The only way to correct this is to steer into the slide and floor it in an attempt to drag the car out of the slide. In most cases, this will have you running wide round the corner and possibly into oncoming traffic.
Basically you have very little control over the back end of a FWD car and thus need all the grip you can get at that end.
Well that's as maybe. But I stick to the point that if your 'loose' the front or back end of the car when you are driving on the public roads you are not driving to suit the conditions.
