#1 is easy: “pay us or we will accelerate your car in a random direction in 24h”. The first round will be scareware, the future may not be.

Can't happen in a tesla, “so even if somebody would gain access to the car, they cannot gain access to the powertrain or to the braking system.”

And how is this any different than we'll kill you in 24h if you dont pay?

How can that be? You can remotely update the system that does autopilot, and autopilot must have control over throttle/brake/steering.

Even shutting off the lights or disabling the wipers can create big problems.

Systems are built in isolation, communication between them is encrypted.

Disabling wipers or turning off the lights will kill us now? Not forgetting this hasn't happened, hasn't been proved to be possible and is all a theory.

Theories are fine but acting as if tesla is activity ignoring this is funny.

Systems being isolated and containing encrypted communication does not mean that there are no vulnerabilities. Otherwise, TLS would be all that’s needed to secure a website.

[Scoundreller]

They’re clearly not in isolation. We’re not talking about storing data, but sending it and receiving it, so if the messages are encrypted, you just need to feed the code that is doing the encrypting and voila.

Disabling wipers and all lights while driving at high speed with the wipers running full blast can be quickly fatal.

If they were we wouldn't be debating this.

Sorry you are wrong.

[Scoundreller]

Not sure which point you were referring to by "they", but we must have different definitions of "isolation".

If one system absolutely requires communication with the other to function, I would never call them isolated.
