More than anything else, this makes the SSH keys a very high-value target.

I may trust Tesla not to crash my car or violate my privacy, but I also have to trust them to sufficiently secure the SSH keys from bad actors who would (or sell them on the black market where they almost certainly would arrive in malevolent and capable hands). The latter is what scares me.

Sometimes, when I consider the quality of the software/systems engineering work that we do, I wonder how everything is not crashing and burning all the time.

Not only that, they can SSH and flash firmware for multiple devices. That in itself made me not want a Tesla anymore.

I mean, they are held to lower standards than random production VMs that I manage at work, and those can't even kill anyone.
