All your engineering expertise does not substitute for real world experience.

I understand the difference between traction and handling. Perhaps you don't understand that at the cornering limit it is a limited traction situation. Applying power coming out of a corner with four wheels is definately superior to applying it with two wheels keeping the car on its intended trajectory.

The same stability is applicable to snowy or icy conditions as well. Applying power with four wheels instead of two is inherently more stable.

Now with the limited power of my Miata the limited slip is probably adequate to apply all power available on asphalt or concrete with the sticky 1.3 G Hoosier tires. The Miata will spin on entry to a corner if the rear breaks traction due to a shock issue under heavy braking.

My Formula ford though with 110 hp and 1100# total weight (including the 200# driver) will spin instantaniously and comprehensively on injudicious power application in a corner even with the limited capablity of an open differential.

Throttle modulation is the only form of traction control available.

If you take the time to do some research you will find that this is a question that has been considered and tested by many of the car magazines over the years.
