I just tested at 23F outside, Temp set to 60F, recirculate on. It lost 0.8% after 30 minutes and 1.6% after 1 hour. So the car could last 2 days if I started with 77% SoC.
Thanks for the data point. Is it a resistance heater or heat pump model?

From the article.
"Using the Nissan Leaf electric car (here) as an example, Dr Collett said: “Say the heating was on constantly at 2kW (which would be unlikely due to insulation of the vehicle), even if you only had half the battery charged, you would still have almost 10 hours of heating."
They must have been talking about a half-empty 40kw Leaf?
Lets say you have a 62kw Leaf and it was down to say 50kw, using their 2kw figure one would have just over 24hrs and again unless the temps were below zero I'd guess more like 1kw would keep the Leaf acceptably warm. I mean think about a 1kw heater in a room the size of the Leaf cabin, I think that would be doable.
Yeah, it would have to be, otherwise, half of the Leaf Plus (let's use 31 kWh just to be nice), would still give you 31 / 2 = 15.5 hours of heating, which at 2 kW you would be roasting inside the cabin unless you had the windows down?
Think about if you brought out a 1500 watt space heater from your house and put it inside your Leaf and set it for "high" and left it running for hours, it would be hot as hell inside the cabin and it's using less power than what the article is talking about.

It seems to happen to those who can least afford it--trying to stretch until payday in a min wage job. Nobody would want to run out of fuel or electrons, a close call is all it takes to put the pucker in your shorts...
Another factor that I don't think has been mentioned is that an ICE engine would need time to warm up to produce hot cabin air. My Leaf gets hot cabin air within ~30 seconds.
Also, an engine at idle may not produce much heat at all. My diesel truck takes a long time to warm up, but once warm the engine does hold heat fairly well. A smaller gas powered car may not do that.

ICE cars are glorified heaters that also happen to convert some energy to useful rotational motion A really efficient ICE car is only 30% efficient, most are worse.
So, any ICE car that can't easily keep the cabin warm while idling has either a clogged heater core or some other cooling system issue.
