Based on context, I'd assume that the loss of efficiency of the batteries in the cold led the vehicle to over-estimate the range of the vehicle. If the car says it has 50 miles of range and the next DC charger is 40 miles away, I could imagine a situation where I'd get 30 miles down the road before the range estimate shows that there's actually only 35 miles of range because you wanted cabin heat.
EVs are weird in lots of ways when compared to ICE, and we're still figuring out lots of the problems that need solving.
If you are in a traffic jam, you lose range because of the heating. For gas cars, that doesn't matter at all.
A 1kw heater (less, given they're all heat pumps these days) isn't doing squat to the range compared to an 80kw motor.
A gas car has to idle its engine to get heat. It's burning fuel constantly.. that's why you frequently see broken down gas cars in heavy traffic.
