Gleason's design for the Torsen doesn't really "sense" anything and
then respond.  The outputs are coupled with what are essentially worm
gears.  By giving the same massive mechanical advantage to each wheel,
you have to lose a bunch of grip before the drive force can overcome the
urge to spin a wheel.

Broken CV == no resistance on that axle so it will spin free.
