This is what happens when you run your battery to 0%
 

Nextmove YouTube channel has a video posted showing what happens when you run the battery to 0%. To summarize, 0% really does mean 0 range. However, when the car is restarted and the battery has had a moment to rest (typical battery recovery), the meter gives a bit more energy available at reduced power output level. Possibly enough to move to a safer parking area or better towing position.

Funny thing is they've spent so many years drilling into the masses that with gasoline "reserve" the ICE cars allows 30-40 miles past the "zero miles to empty" display.
This may catch some off-guard who are used to the "reserve".

Not if they are current or former pilots.
