How does this logic work with electric cars; just cut the range in half?
Electric cars are apparently much better in these situations than gas-powered cars, because you can keep the heat on for hours and hours without using up much charge (or creating any CO). Don't personally know if that's true but it's what I've read.
Google translated a recent P4 article:
The snow weather over southern and western Sweden has had a major impact on traffic and people have been sitting in traffic jams for several hours*, reports P4 Gothenburg.
A major problem has also been electric cars abandoned on the E6 by their drivers. The battery runs out when there is so much heat in the car.
- We will be able to salvage(tow) a lot of electric cars that were on the E6 during the night, says the Swedish Transport Administration's road traffic manager Mikael Salo and believes that this is one of the shortcomings with the new cars.
