The negative replies to this are largely valid, but ignore the fact that we can have multiple strategies at the same time.

I for one would love to be able to take my battery out, swap it, have a few so some are always on solar charge. Be able to take one onto the boat. Use a new one for higher performance special occasion driving, and an old one for bumper to bumper slow commute which I can wrong every last mile out of. Have a few which default to home backup and can support the grid.

The highly optimised around the battery argument is very good. But it doesn't mean that we can't also have a company focusing on interchangeable batteries with a third party market.

Let the buyer decide. Neither solution will get 100% of the market, or zero. Why write one off right now with confidence when both could have a healthy market for the hugely diverse users (ie not just SV nerds)

The fed enforcing interop wouldn't be black and white. Just like Mercedes are allowed to sell super low MPG AMG Sports cars because they also sell lots of small city cars. The fed could encourage things in this direction without being black and white and mandating 100% of batteries be replaceable.

I think the downvotes of the parent comment here aren't what downvotes should be for. He or she brings up a very interesting point

Literally nobody is arguing against some companies being allowed to do that.

And Nio does in China.
