The difference between two-wheel and all-wheel drive is night and day, compared to the difference between winter and summer tires. Even then, it all goes out the door when conditions get icy and the only option is studs or chains, to get any traction.

Chain controls, and really all winter regulations, like snow load factors in buildings and whatnot, are created locally, not by the state. Most politicians are from Southern California, and all the state cares about is air condition efficiency and water usage, as though everyone lives in the desert.
