>You can't have an electrical cut-out that doesn't cut-out certain components.
Nonsense. Even the old mechanical ignition switch simply engages a number of relays and other electrical/electronic controls.
>The reason you need a complete electrical cut-out is for safety reasons (eg fuel leaks into engine bay).
Fuel cutoff relays exist and have been in use since, not long after electric fuel pumps were put into use.
>The ignition switch cutting all power has worked without incident in every other brand for many decades.
In no way is that statement predictive of the efficacy of such a simple scheme going forward with more advanced electronic controls.
>The issue here is GM's incompetence,
No arguments there.
>If anything I think this is an argument that power steering should be limited so that average drivers don't lose control of their vehicles if it fails (I've lost power steering in motion due to an engine stall, it is very scary).
It is limited. It's more properly called power assist. It shouldn't be scary. Power steering is most useful only at low speeds.
