Tesla recommends (I think it's the default?) limiting charging to 80% and when they drain as low as 20% they shut down to protect the battery. You'll need to call a tow truck unless there's a major emergency/evacuation, then they take advantage of the car's cellular connection to unlock the last 20% and allow drivers to use the whole battery.

I don't think the Volt did that. Maybe newer (and more expensive...) GM EVs do though.

Haha what? No that is some serious misinformation. A Tesla might go into a slumber mode when parked for a while, this only means it takes a few seconds to start instead of the instant response if you parked for a short while. , but it will not shut down until sometime AFTER reaching 0%.

Also, there are now two types of batteries for Tesla cars.

The Tesla Model 3 RWD’s battery pack uses the LFP chemistry which Tesla recommends charging to 100% at least once per week. Tesla recommends setting the charge limit to 100% for daily use.

The Tesla Model 3 Long Range and Performance variants uses a different chemistry referred to as NMC. The Tesla Model Y owner's manual recommends setting the charge limit to 90% for daily use. This will minimise degradation and preserve the longevity of the battery.
