i was working in Austria last winter , when i picked up the car , was told it was on winter tyres . I couldnot believe the speed people were zipping around . Temp was - 15 during the day . But will say 2 things , they are prepared and funded for bad wheather , the clearing operation is 24 / 7 . not like this country ( ohh were running out of salt we have had a couple of bad weeks and we have non left ) snow ploughs every were.
2 ) The cold is different , get out of the hotel at 08.00 temp -10 / -17 yet cars never needed scrapping , they were perectly clear . the air just took your breath away , but not once did you ever feel the car was not in control on the roads
