Here in Norway it is common knowledge to not head out into a winter storm or driving over a mountain pass without having a full(ish) tank / charge. It is advised to bring warm blankets, clothes, water and some food. Getting stranded at a moutainpass or in a tunnel waiting for a storm to clear enough to allow the plough truck to lead the way is routine in the winter, it is the rule and not the exeption.

Of course there are always some who do not head the warnings, but they are the exeption to the rule.

This winter we also experienced a sudden heavy snowfall in the south of Norway, which took thousands of drivers by suprise and caused a 10 hour long traffic jam on one of the main highways. Some electric car owners where running low, but to my knowledge they all made it out without getting stranded.

Being prepared is a cultural aspect of winter driving and avoids most problems independent of the energy source used by the car. One advatage of electric cars is their ability to keep warm for hours without expelling any co2, wich have caused some horrible tragedies where people have been poisened due to the fact that the car has been patrly snowed in, trapping the exhaust.
