Magnesium chloride is more corrosive to automobile bodies than rock salt is.I don’t know why the Midwest still uses rock salt on icy roads. There are several non corrosive alternatives. It amounts to local governments destroying everyone’s vehicles. The magnesium chloride and sand/cinders used by my state highway department are non corrosive. Many other western states also use those materials. And no vehicle corrosion.
Your state is arid, with mild winters, very little snowfall, and low relative humidity. That’s why your cars don’t rust.
You use volcanic cinders because you have vast fields of lava fields. That’s not common other places.
Sand doesn’t readily spread at twenty below zero unless it’s mixed with salt.
Magnesium chloride brine is sprayed on the road before the snow even starts. It’s highly corrosive to cars and bridges. Cars are replaceable when they corrode, and deaths aren’t exactly inexpensive or desirable either.
