Well.

To fully charge a leaf at a public fast charging station takes an hour. https://www.nissanusa.com/experience-nissan/news-and-events/nissan-leaf-charging-101.html

My up! can get about 260 miles out of its 30ish liter tank. That is about 1/3rd more than a new leaf. Hardly half the distance.

The electric grid will be fine. This is not the first time it’s expanded because of new technological demand. And I’ve never heard of 5 EVs overloading the grid.

And if the person above could read they’d see that all of these are battery problems, something the original comment said we should have put our focus improving on long ago.
