The only way EVs would have ever worked is if the batteries were removable and interchangeable in short periods of time between makes......and that would be having to forget the other dozen or so drawbacks they have.
That was the way I thought it was going to work - sort of like propane tank exchanges. Hard to see how to make it work. Maybe if we could come up with a fuel source that could be put into a vehicle in a matter of minutes, and used in any year or model vehicle. I may be crazy, but I'm sure we could think of something ......
Let's say a battery is quickly removable and is capable of being replaced in several minutes. The removed battery still has to be rapidly recharged for a future battery replacement. Musk's side show back in the day was just letting people know that Tesla batteries could be replaced.
