I haven't encountered snow since my last manual died but that's my understanding of electronic traction control--give the job to the computer that can do a far better job than any human.

When the computer can outperform a human let the computer do it! Only give control of things where at least some drivers can outperform the computer. And, while not relevant to driving, if there's a grey area let the operator hit an override to use it. (Boeing--the plane does what you tell it even if you go outside the envelope. Airbus--the plane stays in the envelope no matter what you tell it to do. The first makes for broken birds, the second means the pilot in trouble can't decide to risk breaking the bird if that's what's needed. If you need 4g to clear terrain you do it even if the bird is only rated for 3g.)
