Well, to be fair, you can already swap your battery if you're willing to pay for it. You might save a little bit of money in labor costs with the swapping station, I suppose, but I can't imagine it'd be much cheaper than it is now. We'll see I guess.
I thought Elon in that presentation said it would cost almost as much as filling up a 20 gallon tank. Which is why I don't think that swaps your pack with a new one. Or, as pointed out above, you may be expected to have to exchange it back at some point.
