Can someone here explain how the ATRAC and VSC work on my 2000 LC and how/why it is better or equal to having locking diffs.
Thanks in advance.

VSC
VSC assists control lateral slip caused by a driver’s sudden and rapid steering action during high-speed and snow road driving.
TOYOTA: Company > Technology
Since 1997, Toyota has offered stability control – first on its Lexus vehicles and now on a range of Toyota and Scion vehicles.
The stability control system uses sensors to detect if a vehicle is starting to divert from the direction the driver intends. It might be that the back end of the car is starting to swerve, for example, which would take the car off the path the driver wants – not to mention create a very scary spin.
Stability control, typically called vehicle stability control, or VSC at Toyota, detects the problem – often before the driver does – and takes action. Sometimes the situation can be corrected with just a slight, automatic activation of the brakes, or braking at one of the four wheels via the anti-lock brake system.
The driver doesn't accomplish that by touching the brake pedal. The system does it on its own.
If that's not enough because, say, the vehicle is going too fast, the system will reduce engine power. Again, it's not because the driver does anything.
In fact, I kept pressing on the accelerator, only to find it was accomplishing nothing. Basically, the system had taken control of the brakes and throttle to get the vehicle back in line.
But if you've ever experienced a VSC moment, you might have noticed that the system braking can be abrupt and noisy and the engine cutback a bit heavy-handed.
There's nothing smooth or sophisticated in the experience, and that isn't just with Toyota's system. I've experienced it in other vehicles, too.
But that roughness is going away. Toyota's newest version of VSC is called Vehicle Dynamics Integrated Management, or VDIM. The system builds on VSC and integrates an electronic brake-by-wire system so the stability control's automatic braking adjustments are smoother and, it seemed to me, less noisy and abrupt.

interesting to think that you can lose all control over brakes and throttle, no? 
(yet another small step to the Matrix taking over....)
oh, and ATRAC is just the brakes clamping down on wheels that have lost traction to redirect power to the other ones
