"often because the driver simply had no idea how to lock the diff," Most of the locking diffs out there are automatic, like the G80. They're basically a locking limited slip diff. It uses slip between the wheels to throw a cog (for lack of a better term) that locks the diff. It then unlocks (drops the cog) after the torque is unapproved. This is very different to use from the older way of locking diffs via the hubs or the high end electronic switches that enthusiasts use.
