I think the issue is with this example of frictionless back tires. Assume the ideal torque split should instead be 60-40 to prevent slippage due to road surface and put all the torque down that you can ( ie maximize acceleration(t)). In this case, the 50-50 split will either force the rear wheels to spin or force the driver to engage less throttle. It doesn't matter how the "torque appropriation" is carried out, it matters how much of the available torque is actually applied to ground from the engine *without* causing the wheels to slip.
