Downwardspiral, I think you may not have a clear understanding of how Bosch's modern traction control works. Your reasoning makes sense with old school muscle cars and locker diffs, but things have changed in the traction control age.
The TCS monitors wheelslip as compared to steering angle 50 times per second and makes adjustments to each rear wheel brake at that rate. This means that the brakes will attempt to equal out the torque distribution to each wheel every 20 milliseconds. This is very easy to do on dry pavement with identical tires and the effect on the stripes would be seamless to the naked eye.
