All very good points, but why don't the local authorities use salt or some other traction modifier? It's been proven many times that the people will not learn
This is the first winter in at least ten years that the ground has been frozen from November through March. Over that time period it has been very common to get a few inches, then the next day it's 50 deg and melts then cold again.
Well, can't say for other parts, but here the state threw down a bunch of brine, which didn't hold because it all got washed away the night before. The Wednesday all hell broke loose, they dumped down salt so thick it actually caused more problems than good. On I540 the salt melted the snow/ice and then it refroze after it got washed to the sides of the roads. On county roads, they didn't do anything because they assumed people would just stay inside. When I went from Wake County (they plowed and salted and the ice still came back) to Franklin County, you would have thought the roads just disappeared.
In hindsight, people simply weren't prepared. Our upper management bosses told us to head home about 2. Well, it would have been fine if they sent us out at noon. Because it came down fast
. I personally got stuck one year at home. Dirt roads and a lot of snow meant even my truck couldn't make it far. I bought some winter tires, and everyone I knew laughed at me. But it made ice storms a breeze.
But back to your original question, we don't see much by way of ice and snow. It maybe snows two or three times a year, and it's gone in a few days. So having all the things necessary isn't cost effective. So it's brine, salt and plows. And that's it.
That's a pic of one of the roads I was on that day. Notice they did nothing to prep the roads...
