Sounds like jumper cables.

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

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

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".

1) See William Gibson: "The Future is Already Here, it's Just Not Very Evenly Distributed."

That's entirely possible at present, I think? Many electric vehicles can send power out to power appliances. It's called "Vehicle to Load" or "V2L".

And electric vehicles can slow-charge off a wall power socket, so they could get that from V2L. It won't be a common use, but it would work in a pinch to get you enough juice to get to a better charger?

<10kw, so not super fast, but I bet most people are really close to the charging station when they run out.

(But no, I'm not liking that Tesla is taking the typical entitled-ass attitude of avoiding all the standards bodies, doing whatever they want, and expecting others to ratify their standard. If it is that good, it should be readily agreed to by the relevant standards bodies.)

This exists: https://news.ycombinator.com/item?id=41975736 But for Lucid, not Teslas. And also more generally as a use of V2L.
