I thought you were talking about the auto braking/power to wheels to avoid a skid control. On her dash it reads traction control and you have the option of leaving it on or off. Sounds like alot of you are talking about more of a limited slip axle. I came from PA, after 35 years of snow and ice. I drove triaxles in the winter, they have switchs on the dash so you can lock the differentals together, so two wheels on each tandem have power,(only one wheel will spin if you get hung up, then you can hit another switch and lock all four wheels to power on all the tandems. I thought this would be Great in the snow, it is for going in circles. Not to mention you cant steer the thing, it goes straight. It was a gizmo option, if you got stuck, otherwise worthless, the first axle lock was sufficent.
