WI/Milwaukee drivers can handle snow, but they're as bad as everyone else on ice, and worse, ice under snow, and they get complacent because of how aggressively county and muni road workers usually salt, creating a wet grab-layer on the road where the snow slushes out of the way leaving a contact patch not much worse than a rainy day.
We've already had our first slippery day a few weeks back, making this all the more inexcusable.
