"What we're discussing" is a system which is not in the end being rolled out, but Tesla, at an early stage, did mention precisely the issues I brought up.
There was to be the option to keep a newer battery received in a swap (for a fee) but also, somehow, always the possibility of getting your original battery back. How that would actually work if the original battery is in someone else's car half way across the country is left as an exercise!

- mikeash 11y agoThey mentioned them in the context of how they're solved, though. Gresham's Law is about things which are fungible in some contexts but not others. If Tesla charges you a fee to keep your borrowed battery then they're never fungible so it doesn't apply. How it works to always get your original battery back seems obvious to me: they don't put it in other people's cars, they hold on to it for you. If you decide to keep the newer battery, then your original is no longer yours, and you can't get it back anymore. This whole thing seems like a lot of fuss about problems which are pretty easily solved, and are solved.
- greglindahl 11y agoAs the article you point to says, the temporary packs would be owned by Tesla. So no, your original battery wouldn't be in someone else's car. Contrast this with the battery swap strategy of Better Place, in which car owners don't own batteries.
