 yes, all those computer controlled thingies are ultra-cool, no doubt. But
 look at its complexity! Look at the amount of points of failure! Getting
 this all right is hell of a job, progressively.
 And all computer controlled devices are directly prone to oscillations,
 there are tons of "spider bite"s waiting. There are delays between sensing
 and reaction, noticable delays. There would be lot of situations when they
 would annoy.
 Beauty of torsen is its simplicity and instantness, and still its considered
 to interfere with driver.
