I just googled the above. Apparently LSD was the precursor to traction control. Traction control we've got; it supersedes LSD. Don't need no damn LSD.
The VLSD can help in assisting to put the torque where it needs to be. Its best not to judge something you dont know anything about except for a 5 minute google search.
