Put them in a turn and the liklihood decreases because the weight shift is much more complicated. As you have mentioned ABS pulses faster than any human being could consciously "lift" off the pedal due to the reaction time. There is no such thing as a zero second reaction time that when a driver recognizes the wheels locking up that he/she can instantaneous lift and reapply the brakes. On the other hand a skilled driver cannot consistently stay at the edge of locking the wheels... He/she can do it better than we can, but not faster than ABS...

Hi,
Sorry, not buying it. I have demonstarted this and seen it done by professionals. ABS is not even designed to decrease the stopping distance, it's sole purpose is to prevent wheel lock, it does not increase the brakes efficiency. In fact, because the calipers are not clamped continuously (where mechanical energy is transferred to heat energy and expelled from the system), it reduces the brakes efficiency and results in longer stopping distances. And this says nothing of where the threshold is set by the control unit. It can be argued that if you activate the ABS at all, you're already doing it
wrong. It is possible to understand and feel when the car will lockup and thereby avoid it...
Happy Motoring!... Jim'99
