I understand the complexity. I don't understand _this_ particular problem because Ford hasn't paid me to do root cause and critical chain analysis. But I understand the domain of life safety & critical infra systems well enough to know that this is fail.

I never said it was easy, and would appreciate that you not put words in my mouth.

What I do say is; If you can't do it right you shouldn't be doing it and selling it to the public.

Bricking a $50-100k device by pushing a bad update is unacceptable. Saying that bricking is a safety feature is a cop out. Failing to address the problem is criminal.

@johntimaeus @OliverNoble @nuthatch @danluu It’s not bricked: it needs to be connected to an authorized diagnostic tool. But clearly you don’t want to learn and I don’t want to hear uninformed opinion, so on that basis I’m muting this.

If the vehicle will not execute any basic functions, like being able to move under it own power in some direct law, limp home mode, then it is, by definition, bricked.

@johntimaeus @kentindell @OliverNoble @nuthatch @danluu it's possible that they are required to brick the vehicle in the case of a failed update.

Anything else could involve the vehicle running in an indeterminate state or with a known issue. Both could be liability issues

Of course ideally the update shouldn't fail but that's impossible to guarantee.

ICE cars have a limp home mode. No cruise control, no traction control etc etc, but you can get home.
