Now think about a field you know. Maybe laptops or phones.

Would a standardised battery block in laptops work? The same battery would work in a Frame.work, System76, MacBook air, MacBook pro, a Lenovo Thinkbook and whatever gaming monster there is from Asus.

Sounds stupid, right? It's just as stupid for cars.

And if laptops had battery swapping, would you swap your brand new battery, but empty, to a random one at a swapping station? Would you trust the people and systems that the battery hasn't been tampered with and is in good working order?
