I trust nothing less than the best. The wet and fluctuating climate here makes ice especially unpredictable.
One day you have +6-7°C and light rain. Then the clouds clear up in the afternoon and radiative cooling brings the road surface below freezing, turning that water into black ice. Uneven patches of road surface catch water and turn into smooth ice patches
What I just described is a VERY common situation during the winter here. In fact, it's a risk factor from maybe October to May, if it's colder than usual. And the high humidity year round means that even when it's way below freezing and no precipitation, with streets cleared of snow, ice still forms during the night due to sublimation of the massive amounts of water vapour in the air. Dry and clear streets are very rare during the colder half of the year.
That said, however, I actually took the studded tyres off yesterday...
