The article is pretty light on details and pretty heavy on empty phrases like "To each their own, we guess. Like it or hate it, owners are free to personalize their vehicles". As a Hacker News reader, I'm mostly interested in how this "hack" works, but the article unfortunately doesn't offer any details on that (ok, at least they warn you that the video is in Mandarin, so a few seconds saved there).

Agreed, the article is more like throwing a lit match into a barn than educating a good hacker. I think there's some good discussion happening here about design but on reflection this whole thread probably doesn't need to exist because nobody is learning how to hack their Tesla's dashboard.

Yeah, how does it work!?

There has been a set of buttons available for a while from a popular aftermarket vendor (https://abstractocean.com/products/s3xy-buttons https://abstractocean.com/products/s3xy-buttons) that interface through the OBD2 port. There is a good amount of reverse-engineered information out there on Tesla CAN bus messages (e.g. https://github.com/joshwardell/model3dbc https://github.com/joshwardell/model3dbc). If you have some coding and electronics experience, it'd pretty much be a matter of gluing some libraries together. Probably easier than gluing the physical buttons to the car.

Almost certainly via wiring into the CAN bus. There's quite a few aftermarket addons that require you to run a line to the internal CAN bus to have certain things function (like popping the trunk, for instance). I've also seen some Bluetooth based ones that require using your phone, which then relay to the Tesla app to perform functions. Not sure who's using those quite frankly, seems like a bad solution. Also this panel appears to do thing you cannot do in the Tesla app, so I don't think it's using that method.
