It’s really unnecessary cost and complexity. There’s no reason for it

Even without counting the newest high speed charging vehicles

• 300+ mile range is now common. Important that it now matches how long most people can sit
• 20–>80% charging is already fast
• 10-20 minute stops can keep you driving, matching a bathroom break or fast food break
• structural batteries really help with weight and efficiency

I really don’t see how swappable batteries would help with charging speed or cost, by any noticeable amount

Even worse, how could you scale out? We’re already taking way too long building out chargers that are arguably just a power outlet. How could we possibly add the inventory problems of a different battery per vehicle, special automated lifts able to handle like a ton of battery, and scale it out to every highest, city, town? It’s just not possible
