Unless there was a helicopter hovering up ahead with a LIDAR terrain mapping unit feeding 3d simulations to some on-board computer and it happened to be running the right simulation model, I cannot see how any cyber-widget could have come to the same conclusion as I did.
It wouldn't. Instead, it would have applied power to any driven wheels which could make use of it, and applied braking to any slipping wheel individually, which you cannot do. You probably would have never noticed the loss of traction to begin with if traveling at typically low speeds.
AFAIK heavy trucks don't have to have the driving aids which are now mandatory on all passenger cars in the developed world, but one day they will.
