This is my favorite little piece of data related to winter driving and traction control (TC) (which is nowadays often controlled jointly w/ ESC via the ESC button), the good stuff starts at 1:55 mark:

In summary, studless winter tires reach maximum grip force at 40-60% slip. This kind of slip is not reachable if you have TC enabled in your vehicle, which limits the slip to max 15-20% or so. By disabling the TC/ESC and spinning the wheels in a controlled fashion one can nearly double the traction force from ~250 daN (deka Newton) to ~400 daN.

I have 'always' known this just by experience, but nice to see a proper data proving the point :)

Some manufactures wont allow you to fully turn off the ESC. I'm happy that Hyundai does!

Great video! Interesting (and helpful) information for the consumer. If I was living in Canada, I would be all over this.
