Tesla figured out how to do it and implemented it.

Problem is, nobody wanted it. They would rather wait to charge than turn in their personal battery, and later come back for it.

Would you want it? Would you turn over your decent, brand new battery at some charging station?

What's interesting is that they did it differently with the cybertruck. You can buy an additional battery that I believe is swappable.

They didn't really try to bring it to market. If the battery was just leased while it was installed in your vehicle (so you were only paying some reservation charge and a use fee instead of the full up front price), you might not feel so attached to it.

Do you have a source for "nobody wanted it"?

From what I can tell they showed it off to get some tax credits, then decided not to deploy it anywhere (but keep the money of course).
