I believe this is a great safety feature, not just the Ice Warning but the outside temp in general. I live and drive in mountainous areas where the road and air temps can vary widely depending on elevation and how much sunlight the area gets. During a snowsquall a few weeks back, the outside temp went from +2°C in Greenville to -3°C by the time I climbed to Hendersonville and knowing so meant I knew that the snow falling was going to stick and accumulate on the interstate.
