All vehicles are different. Some gas hogs wouldn't last as long as, say, a Honda Fit sitting idling running a heater. Some EVs have better systems than others and different sized batteries. Some estimates I've seen say a Tesla could run 3 days on a full charge.
...there’s a ton of misinformation out there about electric vehicles and much of it centers on whether you’re likely to run out of juice in a traffic jam. Research has shown that EVs can preserve their battery power rather well even if they’re stuck in traffic with music, air-con and headlights on.
A study from Which? says you can relax. The consumer group based their findings on data taken from a Volkswagen ID.4 EV by running the air conditioning and stereo and playing video in the rear seats for one hour. Over the course of the test, the battery was drained by just 2%. Assuming you began with a full charge in the VW battery, it would take a traffic jam almost 50 hours long to completely drain the battery.
And the test was pretty exhaustive as the air conditioning was placed on its maximum setting, the headlights were on in their automatic setting, both front seat heaters were cranked up to a maximum setting, a tablet was streaming a film, and it was plugged into the USB charging socket.
Without the internal combustion engine to produce heat for cabin comfort, electric car heaters must work harder to maintain a comfortable environment for the passengers. In answer to that problem, some electric cars - and likely more in the future - will use heat pumps which operate far more efficiently than regular air conditioning and heating systems. -https://www.autoevolution.com/news/the-arguments-against-a-nation-packed-with-electric-cars-and-trucks-171878.html
Plus there is a lot less, if actually no, possibility of carbon monoxide poisoning. Give me an EV or an ICE car every time.
