Tesla recalls 380k vehicles in US over power steering assist issue

You're talking about the MCU (media control unit), which is completely isolated from the critical driving functions of the vehicle. As its name implies, this unit mostly drives the vehicle's entertainment functions. It's actually incredibly confidence-inspiring to me to know that the MCU can go entirely offline and the vehicle continues to function at 100%. This seems like it must be table-stakes for all vehicles, but I've seen more surprising things.

I'm not sure why you mention cell coverage, given that it is entirely unrelated.

Good to know the legally mandated speedometer is just media (I jest a little).

> why mention cell coverage

When the culprit is a borked OTA, it's very non-obvious that it'll behave correctly without another remote signal, and the fact that you're allowed to drive your car might only be because you haven't shut it off yet (immediate safety outweighing the danger of driving a partially functioning vehicle).
