Agreed. And if ice were always a glossy sheet that covered the entire roadway uniformly and advertised its presence perfectly, that might be the end of the story.
Sometimes the ice is in a thin covering that you can barely see unless the lighting is just right. Sometimes it's in patches that you won't notice until it's too late. What's the solution in those cases? Picking a speed that's "safe" for ice and driving that speed whenever there theoretically
might be ice, whether you can see it or not? You'd be driving around half the posted speed limit on a mostly dry highway. Fair enough, but... good luck with that.
...And
even then, you'd STILL be better off with winter tires than with all-seasons. Hitting an ice patch at 30 MPH is better than hitting it at 60 MPH, but it's still no joke.
Similarly, even if you ARE driving on a uniform sheet of ice that you know is there -- let's not bother with the obvious question as to why on earth one might do that -- the safety margin/safe speed is MUCH higher with winter tires than it is with all-seasons.
In any winter conditions, the only speed at which all-seasons are as safe as winter tires is 0.0 MPH.
Thanks for the education on road ice. Gee, I never knew any of that even living in NH my whole life.
My POINT is you shouldn't be driving that fast when icy conditions are or MAY BE present. I don't care what you have for tires. If the roads are or could be icy slow down. Period end of story.
