You know what? You're right. That's literally jumper cables.

But no, I don't think Tesla is doing those.

Tesla vehicles do not currently support V2L or V2G, although many other EV makes do.

But it does seem that Tesla is planning to do those some time:

Honestly that would be awesome. I still dream of autonomous vehicles auto-convoy and link up for efficiency. Just quietly become a train as needed.

Why is it that when describing EV technology, HN people have a tendency to frame it as "imagine if it could, that would be amazing if"

While describing stuff that exists in some form, and usually has existed for years already now.

It's not evenly distributed new tech for sure (1). But maybe it's the false assumption that "if it was anywhere, I'd be among the ones to see it early".
