AdvanceTrac is sort of an electronic "limited slip differential". It senses when one of the drive wheels starts to spin and then partial applies the brake to that wheel which forces more torque to the opposite wheel.
Not as good as a true limited slip differential, but it is essentially "free" (software inside the ABS). The light on my dash blinks when it is operating (on snow), not that I can tell much.
I think it is now standard on all Ford vehicles.
Electronic Stability Control (ESC) or Roll Stability Controls (RSC) are added on all light vehicles. This is (or will be very soon) a government mandate.

I don't believe that statement.
Chains means chains. No substitutes.
