Steve, totally agree about the tires, should be the law for winter driving to have snow tires (in some Canadian provinces it is now), but as good as snow tires are, studded snow tires are that much better on any icy surface. All you need is one time not getting stuck, or being able to stop, or steer, potentially saving lives and vehicles and the savings are immense.
Also total agreement that the salt on bridges (and vehicles), does far greater harm than help. We can’t afford to keep up with the infrastructure damage. On that note, why on earth aren’t they using stainless steel rebar and structural steel in bridges in salt country anyways? Doubling the lifespan of a bridge far outweighs the cost of stainless.
