Interesting to see the 8C in the snow! Would probably never happen here. We have half a meter snow in the area exept on the roads. So this is less than everyday condition here at this time of the year.
In contrast, last year in London they had to close the airports for several days because of snow blizzards. Here for the same precipitation, the closing was for 4-5 hours only. Much more accustomed here to such conditions!
However I wonder, do you have winter tires in you area, or did you drive with summer tires? Maybe the concept of summer/winter tires is strange even?
