Clearly, there was a demand for these kind of systems!
Absolutely false on the braking - AWD/4WD has nothing to do with stopping capabilities. On snow and ice, the deciding factor will always be your interface with the surface - your tires. Once you consider that, it's actually less advantageous to have a heavier, imbalanced vehicle (such as an SUV) when it comes to emergency maneuvers and stopping. When I drive the mountain passes here in the Cascades (which is the snowiest place in the world, mind you - Mount Baker and the North Cascades can receive over 100 feet of snow per year), the vast majority of accidents and stranded vehicles I see are SUVs. Why? Because drivers of said vehicles believe that they can defy physics:

"I can start better so therefore I must be able to stop better."

Please.
