And that is the beauty of computer controls. Knock on electronics all you want - but how else can you get one relatively simple system (ABS sensors, computer and brake actuators) performing so many duties (ABS, traction control/limited slip, stability control) in such a variety of conditions (highway, off-road).
Now all we need is to switch to electric drive - no complex transmissions, flat torque from 0 to max...
