I just want Hyundai’s magic built-in snow chain wheels.

Hyundai has a new concept for dealing with snow driving: shape-changing, bent memory alloy rods, integrated with a “wheel and tire assembly,” that extend out to act like snow chains when a current is applied.

It’s a very cool idea, though I doubt these will be cheap to fix when they go flat. Still, probably a less fraught approach than spinning chain wheels under your car.
