Something I learned years ago about the SVX is that at low speeds in slikery conditions, the ABS can lockup all 4 wheels before you come to a complete stop. We'd like to think that ABS works perfectly down to 0 mph, but unfortunately it doesn't. Since the ABS uses speed differentials between the wheels, when all 4 wheels are locked, it thinks that the car is stopped whether it actually is or not. When you sense this happening, immediately let go of the brakes and allow the tires to regain some traction, then steer away from the obstacle and/or apply light brakes if possible. Otherwise...well, you already know what happens otherwise.
