Do you actually know how ASC works? Did you ever have it on your bike? I didn't think so. So, here goes: ASC works with skidding sideways as well as straight. It detects tiny differences in spin between front and rear wheel, no matter what wheel, and reduces throttle in a millisecond, thus reducing the chances of the skid getting out of control. If the front wheel goes slipping, it will slow down, ever so slightly, and ASC will detect that. It is not foolproof, and nobody ever pretended that it replaced common sense and skill, but it is good to have as a safety plus. I know it helped me out a couple of times, when I went skidding and it stopped almost instantly without me even having the time to react on the grip. Of course, losing the front is more problematic than the rear, but ASC may help. Hey, if it's good for MotoGP riders, why not for us, mere mortals?
