Despite the global climate change, one of the serious consequences is that in some regions there are rainy days in plain winter instead of snow.
You still need to be careful, because rainy roads below 0 Celsium Degrees are turning into a dangerous skating waltz.
It might seem when looking at it from a balcony, but when you are in the car, it's SCARY.
Remember: Do not try to suddenly push the brake, it won't work. Hold the wheel and search for an escape angle de get into and escape the slide road. It's safer to "bump" into a bush, than getting squeezed between a bus and another car.
